Question

Jerry is making an investment, from which he wants to make a certain amount of interest. Jerry knows he can use the formula 1= Prt, but he wants to find out how long it will take him to earn the amount he needs. Which equation correctly rearranges the formula to find the time needed? A. 1= ? RE ili ITE B. 1= € hilli C. (=1-P- r D. r=T +P +7​

Answer 1

`T = (I)/(PR)`

Explanation:

Given

`I = PRT`

What the question implies is that, we make T the subject of formula.

In other words, solve for T

We have that:

`I = PRT`

Divide both sides by PR

`(I)/(PR) = (PRT)/(PR)`

`(I)/(PR) = T`

Reorder

`T = (I)/(PR)`
