He pays an additional $4 each time he attends a class
with a trainer. Last month, he spent $76 total. How
many classes did he attend with the trainer?

8 classes
19 classes
16 classes
12 classes
14 classes

Answer :

Answer: 14 classes

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

76=4x+20

Step 2: Flip the equation.

4x+20=76

Step 3: Subtract 20 from both sides.

4x+20−20=76−20

4x=56

Step 4: Divide both sides by 4.

4x

4

=

56

4

x=14
