Mary borrowed $4,500 to help pay for college. If the bank
charges a 5.5% annual interest
rate, how much interest will
Mary pay after 4 1/2 years?

1113.75

Step-by-step explanation:

The formula for simple interest is as follows: Simple interest = principal balance x interest rate x term of the loan

P=4500

i= 0.055

t=4.5

multiplying them together we get

1113.75

The reason that this is simple interest is because compound interest increases over time as an exponential

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

7,24
