What is the finance charge on $13,300 financed at 7.9 percent for 4 years if the monthly payment per $100 is $2.44?
luda_lava [24]

If you borrowed $100, then your monthly payment is $2.44

If you borrowed $200, then your monthly payment is 2*2.44 = 4.88

etc etc

We can set up a proportion

2.44/100 = x/13300

to figure out the monthly payment x. Cross multiply and solve for x

2.44*13300 = 100*x

100x = 2.44*13300

100x = 32452

x = 32452/100

x = 324.52

So the monthly payment is $324.52

An alternative way to get this monthly payment is to apply 2.44% to 13300, which is another way to view the phrase  "monthly payment per $100 is 2.44"

------------------

There are 48 months in 4 years (start with 12 mon = 1 yr, then multiply both sides by 4) so we multiply 48 by the monthly payment to get the result 48*324.52 = 15,576.96. This is the total amount you have to pay back which is the principal plus interest.

Subtract off the principal (amount borrowed) to find the interest or finance charge: 15,576.96 - 13,300 = 2,276.96

Answer: Choice B

How many times as great as the value of the digit 3 in 47,235 is the value of the digit 3 in 2,438,017
pashok25 [27]

Answer:

10^{3} times

Step-by-step explanation:

The value of 3 in 47,235 is 30 (ignoring the number that follows, 5)

The value of 3 in 2,438,017 is 30,000 (ignoring the numbers that follow)

The value of digit 3 in 2,438,017 is \frac{30,000}{30} = 10^{3} times greater than the value of 3 in 47,235

Roger gets \$40$40dollar sign, 40 per day as wages and \$4.50$4.50dollar sign, 4, point, 50 as commission for every pair of shoe
jek_recluse [69]
Let y be the total money earned in a day and x be the pairs of shoes sold.
y = 4.5x + 40

Putting y = 112

112 = 4.5x + 40
x = 16 pairs of shoes must be sold to meet the requirement.
