Four sisters bought a present for their father. They received a 10% discount on the original price of the gift. After the discount was taken, each sister paid $9.00. What was the original price of the gift?

Answers

Answer 1
Answer:

Answer:

The original price of the gift was $40.

Step-by-step explanation:

Let the original price of the gift be = x

Discount of 10% on the gift and each sister paid $9 means a total of 4*9=36 dollars

We can write this information mathematically like :

x-0.10x=36

Solving for x now;

0.90x=36

x = $40

So, the original price of the gift was $40.
Answer 2
Answer: 9 dollars represents 90% of the cost. Divide 9 by 0.90 to get the original price, 10 dollars

How to write 25/4% as a decimal

Answers

First let's reduce 25/4

25/4 = 6 1/4

Now we can convert 1/4 to hundredths

6 1/4 = 6 25/100

Now just rewrite 25/100 according to place value (twenty-five hundredths is .25)

6 25/100 = 6.25

Now don't forget we are still in percentage (25/4% = 6.25%)

convert to decimal by dividing by 100 ( move decimal 2 places to the left).

6.25% = .0625
To write 25/4 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 25 by 4 what we write down as 25/4 and we get 6.25
And finally we have:
25/4 as a decimal equals 6.25

The Greens want to put an addition on their house 18 months from now. They will need to save $10,620 in order to achieve this goal. They set aside the same amount each month, and after a year discover they have saved $6,120. The Greens must adjust their plan in order to meet their goal, so they came up with the following options: Option A: Stay with saving the original amount each month but put the addition on one month later than originally planned. Option B: Increase the amount of money they save each month by $120 from their original plan.

Answers

Answer:

So he should go with option B

Step-by-step explanation:

The Greens will need to save to achieve his goal  = $10,620

After one year if they have saved $6120.00 this means they save

6120 ÷ 12 = $510 per month

This means after 18 months they save

510 × 18 = $9,180 only. this is not enough for his goal.

so if he increases the amount of money by adding $120 from their original plan he could achieve his goal

= 510 + 120 = $630 per month

= 630 × 18 months = $11,340

So he should go with option B.
option b. is what I would go with
