Question

A fifth grade math question, I saw a person solving it but it didn't made sense. Can you explain how to solve it?

Answer 1

So in terms of dollars and cents, 5 1/2 = 5.50. 50 cents is half of a dollar.

It was $5.50 for the sandwich, and $2.50 for the drink.

Add the total cost of the meal, then subtract this from the $10 Cheryl used to pay for the meal.

5.50 + 2.50 = 8

10 - 8 = 2

Cheryl's change was 2 dollars. In fractions, this would be expressed as 2. In dollars and cents, it would be $2.00 (2 dollars and zero cents).
