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>

What is ​ BC ​ ? <br><br> Enter your answer in the box.<br><br> units
Vladimir79 [104]

Answer:

BC = 25

Step-by-step explanation:

AB = AC since it is an isosceles triangle

4x+1 = 2x+23

subtract 2x from each side

4x-2x+1 = 2x-2x+23

2x +1 = 23

subtract 1 from each side

2x+1 -1 = 23-1

2x = 22

divide by 2

2x/2 =22/2

x =11

BC = 3x-8

BC = 3(11) -8

BC =33-8

BC = 25
