Gerry borrowed $7500 at a simple interest rate of 9% for 4 1/2 years to buy a car. How much simple interest did Gerry pay?

the answer is $3037.50

Step-by-step explanation:

%9 = 0.9

by multiplying 0.9 to 7500 we get 675

once we get this we must multiply it by the number of years

4 and 1 half or 4.5 times 675 gives us our answer my friend ;)

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
