Additiona and Subtraction - Elementary Math

John’s mom gave him $12 to spend at the movies. He spent $3.75 to buy his movie ticket. During break time, he bought popcorn for $1.45, a drink for $1.35, and candy for $1.80.
How much money was left for John to return to his mom.

a. $1.10
b. $2.25
c. $3.65
d. $3.95

Answer : c

Explanation:

The first step is to find out how much money John spent at the movies by adding all his expenses:
$3.75 + $1.45 + $1.35 + $1.80 = $8.35

To find out how much money he had left we must subtract the total expenses from his original $12 that he started with:
$12 - $8.35 = $3.65
