Question

If $10,000 is invested in an account at 4.8% annual simple interest, how long will it take for the account balance to grow to $11,200?

I am confused. How do you do this?
Ms. Sue
I = PRT

1,200 = 10,000 * 0.048 * T

1,200 = 480T

_____ years = T

Where did you get 1,200?
Ms. Sue
11,200 - 10,000 = 1200 >> interest
