Question

Carlos bought a new computer printer for $110.50 and some ink cartridges

for $8.25 each. He spent a total of $176.50.

The equation $176.50 = $110.50 + $8.25c can be used to solve this
problem. Which two mathematical operations do you need to perform in
order to solve the equation for c?

A. addition and multiplication

B. division and multiplication

C. subtraction and division

D. multiplication and subtraction

Answer 1

The answer is C.) subtraction and division
This is because to solve for C you need to isolate it. So you subtract 110.50 to both sides and then divide the product by 8.25 to get C. Therefore you subtract and divide to solve the equation for C.
