Zac invests $3500 at 8% p. a. simple interest for a period of time, to produce $210 interest. For how long did he invest the money? Please help me in the steps to finding the answer and also the solution. Thx

9 months

Step-by-step explanation:

simple interest ( I) is calculated as

I =

P is the principal, R the rate of interest and T the time in years

Here I = 210, P = 3500 and R = 8, thus

210 = = 35 × 8T = 280T ( divide both sides by 280 )

0.75 = T

Thus T = 0.75 years = 9 months

The money was invested for 9 months
