For this week only, you can buy a Dell for $2988, including taxes. Included in the offer is a finance option for 4 years at an annual percentage rate of 3.5%. Find the monthly payment.

Answers

Answer:

$66.80

Step-by-step explanation:

The monthly payment can be computed using the pmt formula in excel spreadsheet as shown below:

=pmt(rate,nper,-pv,fv)

the rate is the interest rate of 3.5% divided by 12 months to show interest rate per month

nper is the number of months it would take to complete the payments which is 4 years multiplied by 12 months i.e 48 months

pv is the cost of the gadget at $2,988

fv is the sum of all month payments which is not unknown

=pmt(3.5%/12,48,-2988,0)=$66.80

If a train travels m miles in h hours and 45 minutes, what is the average speed in miles per hour ?a)  m / (h + 3/4 ), b) m / 7h, c) m ( h + 3/4 ), d) ( m + 45 ) / n, e) h / ( m + 45 )

Answers

Speed = (distance covered) / (time to cover the distance).

Time = 'h' hours and 45 minutes.
45 minutes is 3/4 of an hour. (or 0.75 hour)
Total time is (h + 0.75) hours.

Speed = 'm' / (h + 0.75)

That's choice-'a'.
s=m \ miles\n t=h \ hours \ 45 \ min=h+0.75 \ hours\n v=(s)/(t)\n v=(m)/(h+0.75) =(m)/(h+(3)/(4)) \Rightarrow A

If a goat is reduced by 19% in a sale to £25.92, find the original price

Answers

Answer:

32 dollars

Step-by-step explanation:

Given that selling price of a goat after reduced by 19% is 25.92.

We have to find the original price of the goat.

Let original price = 100

Reduced %          =  19

Selling price         = 81

81 dollars is equivalent to selling price of 25.92 $

100 dollars is equivalent to selling price of 100(25.92)/81 = 32 $
