Question

Isabella's graduation picnic costs $3 for every attendee. At most how many attendees can there be if Isabella budgets a total of $15 for her graduation picnic?
Please get it right.

Answer 1

Answer: At most 5 people

Explanation:

Each person costs $3, so x of them cost 3x dollars. The x is a placeholder for some positive whole number.

We could do guess and check to see when 3x = 15 is true, or we could divide both sides by 3

3x = 15

x = 15/3

x = 5

This means 5 attendees will cost $15.
