Question

Assume that all interest is simple interestBerger Car rental borrow $8500 at 4% interest to cover the increase cost of the auto insurance find the term of the loan if the interest is $170.

Answer 1

we know that

The formula of simple interest is equal to

`I=P(rt)`

In this problem

we have

I=$170

P=$8,500

r=4%=4/100=0.04

t=?

substitute given values in the formula

`\begin{gathered} 170=8,500(0.04t) \\ Solve\text{ for t} \\ t=(170)/(8,500*0.04) \\ t=0.5\text{ years} \end{gathered}`

therefore

0.5 years=6 months

The answer is 6 months
