The simple interest formula is i = prt, where i represents simple interest on an amount, p, for t years at a rate of r. the equation solved for p is p = . what is the amount of money, p, that will generate $40 in interest at a 10% interest rate over 5 years? $60 $80 $90 $100

we know that

The simple interest formula is equal to

where

I represents simple interest

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

Solve for P

substitute the values

therefore

the answer is

i would go with the first one

step-by-step explanation:

hope this

b.an increase in a causes b to decrease
