The formula i = prt where i = interest, p= principal, r= rate, and t= time is used to calculate the amount of simple interest earned. solve this formula for t.
a. t= i pr
b. t = i - pr
c. t = i/pr
d. t= ipr

ANSWER



EXPLANATION

We were given that the amount of simple interest earned is given by the formula,



The above formula is an example of a literal equation.

We want to solve this formula for .

But we can observe that the product of two letters are multiplying the letter
.

So we multiply both sides of the literal equation by the reciprocal of which is to obtain,



This implies that,



We can rewrite this as,



Therefore the correct answer is C.
