Miles and Nick each separately apply for and receive loans worth $5,000 apiece. Miles has a very good credit score, so his loan has an APR of 7.75%, compounded monthly. Nick’s credit score is rather low, so his loan has an APR of 13.10% interest, compounded monthly. If both of them repay their loans over a four year period, making equal monthly payments based on their own loan, how much more will Nick have paid than Miles? (Round all dollar values to the nearest cent.) a.$619.68 b.$267.50 c.$1,609.57 d.$1,070.00

Answers

Answer:

Ans. Nick paid $619.68 more than Miles (exactly $619.54). So the answer is A)

Step-by-step explanation:

Hi, first we need to find the equal monthly payments for both, Miles and Nick, for that, we need to find the effective monthly rate (because the payments are going to be made monthly), also, we need to convert that 4 year period into months. After doing all that, we need to use the following equation and solve for "A".

Present Value=(A((1+r)^(n) -1))/(r(1+r)^(n) )

Where:

A= monthly payments

r= rate of interest (for Miles is 0.075/12=0.006458 and Nick 0.131/12=0.010916)

n= number of periodic payments (both are 4*12=48 months)

First, let´s find out how much money Miles has to pay every month.

5,000=(A((1+0.00645833)^(48) -1))/(0.00645833(1+0.00645833)^(48) )

5,000=A(41.1594758)

A=121.48

So, Miles has to pay $121.48 every month, for 48 months, that is a total of $5,830.98 (121.48*48=5,830.98)

Now, let´s do Nick

5,000=(A((1+0.01091667)^(48) -1))/(0.01091667(1+0.01091667)^(48) )

5,000=A(37.2063189)

A=134.39

So, Nick has to pay $134.39 every month, for 48 months, that is a total of $6,450.52 (134.39*48=6,450.52)

The difference is 6,450.52- 5,830.98=619.54

Means that Nick has to pay $619.54 more than Miles. To your answers, the closest is A) $619.68.

Best of luck
Miles:7.75% (0.0775) x 5,000 = $387.5 x 4 = $1550 (over four year period)Nick:13.10% (0.131) x 5,000 = $655 x 4 = $2620$2620 - $1550 = $1,070 (rounded to nearest cent)So the answer is D.

The table shows the amount earned for washing cars. How much is earned for washing 25 cars? 3 cars=$13.50, 6 cars=$27, 9 cars=$40.50, and 12 cars=$54

Answers

You need to find out how much it costs to wash one car, so:

3×=13.50
Divide both sides by 3.
x=4.5 per car. 
Now multiply 4.5 by 25 which should give you $112.50

131 is what percent 2,400,000?

Answers

Let the percentage be 'x.'
(x)/(100)*2,400,000=131 (x percentage of 2,400,000 is 131).
(x)/(100)=(131)/(2400000)
x=(131*100)/(2400000)
Therefore, x=13100/2400000
x=131/24000 
If you want to further convert it into decimals, 
x=0.005458333333.....
Therefore, 131 is 131/24000 or 0.005458333333........% of 2,400,000.
Let the percent be x.

According to question,

x / 100 * 2400000 = 131

or, 2400000x = 13100

Thus, x = 13100/2400000

= 0.005 %

Thus, 131 is 0.005 % of 2400000

Guillmero wants to purchase a new controller for his video game System. He has a $10 off coupon for big electronics. At costmart there is a 25% off sale on any item . regular price for the controllers at both stores is $49.99. Write an inequality and tell where guillermo will get the better price.

Answers

If you would like to know where Guillmero will get the better price, you can calculate this using the following steps:

a coupon: $49.99 - $10 = $39.99

Costmart: 25% of $49.99 = 25% * 49.99 = 25/100 * 49.99 = $12.4975 = $12.50
$49.99 - $12.50 = $37.49

Guillmero will get a better price at Costmart.

In hoping to make it onto the school's Gold Team, Bryan, Eli,and Damien took golf lessons over the summer.Bryan signed up to take 4 lessons with a semi-pro instructor, and each lesson cost $32.00 for a 45-minute session. The instructor advised Bryan to buy a bag of bulk practice balls to use during his lessons. After buying a bag of 32 golf balls, the total cost for his lessons and golf balls is $132.48.
Eli signed up to take 6 lessons with a pro instructor, and each lesson cost $52.00 for a 1-hour session. Eli bought a bag of bulk practice balls to use during his lessons. After buying a bag of 40 golf balls, the total cost for his lessons and golf balls is $319.20.
Damien signed up to take 5 lessons with pro instructor, and each lesson cost $28.00 for a 30-minute session. Based on the instructor's advise, he bought a bag of 24 golf balls to use during his lessons. The total cost for his lessons and golf balls is $144.08.
Place the students in order from the least amount to the greatest amount that they paid per golf ball.

Answers

bryan: 32*4 = 128

132.48 - 128 = 4.48

4.48 /32 = 0.14 per golf ball

Eli: 52 *6 = 312

319.20 - 312 = 7.20

7.20 / 40 = 0.18 per golf ball

Damien: 28*5 = 140

144.08 - 140 = 4.08

4.08 / 24 = 0.17 per ball

A piece of string is 325 centimeters long. You need the string to be 1 and 1/4 (1.25) meters long.

How many centimeters should you cut off?

Answers

It would be 200cm, because 100 cm is 1 meter, and 1.25 would be 125 cm.  So if you subtracts 125 from 325, you get 200 cm.
