What is the finance charge on 13,300 financed at 7.9 percent for 4 years if the monthly payment per 100 is 2.74?
Julli [10]

To answer this question we have to first determine how many times 100 can go into 13,300. To find this we do the following:


<span>$13,300/$100 = 133</span>


<span>Now we simply multiply the result by $2.74:</span>


<span>$2.74*133 = $364.42.</span>


<span>Finally we just multiply that by the total number of payments which are (monthly payment, 12 months in a year, for 4 years).</span>


<span>$364.42*(12*4) ---> $364.42*48 = $17,492.16.</span>


The correct answer is choice 4.) 17,492.16


<span>I hope this helps, Regards.</span>

a vehicle uses 1 1/8 gallons of gas to travel 13 1/2 miles. at this rate how many miles can the vehicle travel per gallon of gas
elena55 [62]

Answer:

The vehicle can travel 12 miles per gallon of gas.

Step-by-step explanation:

  • The number of gallons used by a vehicle = 1 1/8 gallons

i.e.

1\frac{1}{8}=\frac{9}{8} gallons

  • The number of miles traveled by a vehicle = 13 1/2 miles

i.e.

13\frac{1}{2}=\frac{27}{2} miles

Thus,

Total Gallons =9/8 gallons

Total Distance in miles = 27/2 miles

Hence:

Unit Rate = [27/2 miles] / [9/8 gallons]

                = 12 miles per gallons  ∵ \frac{27}{2}\div \frac{9}{8}=12

   

Therefore, the vehicle can travel 12 miles per gallon of gas.
