Question

Question 1 1) Three friends split the cost of a pizza and a salad. The pizza costs $15 and the salad costs $6. 1) Which expression can you use to find how much each person owes? (15+3)+6 (15+6) + 3 15+( 63)

Answer 1

3 person will split the TOTAL COST.

TOTAL COST = pizza cost + Salad cost

So, we can write:

TOTAL COST = 15 + 6 = 21

Since 3 people are splitting it up, we have divide the total cost by 3, so we have:

(15 + 6) / 3

This is the 2nd expression.
