Question

Blake, Chang, and Grace together sold 71 tickets for the school banquet. Blake sold 27 tickets and Chang sold 28 tickets. How many tickets did Grace sell?

Answer 1

This is a simple subtraction question, the formula is 71 ( total tickets )
71 - (27 + 28) = 16
16 is the how many tickets grace sold

Answer 2

The answer is: Grace sold 16 tickets.

Explanation:

We have a total of 71 tickets sold between 3 people. Blake sold 27 tickets and Chang sold 28 tickets. Adding those sold by Blake and those sold by Chang, gives us: 27 + 28 = 55, if that amount is subtracted from the total sales that are 71 tickets, the result would be: 71 - 55 = 16, which would be the tickets sold by Grace.

The answer is: Grace sold 16 tickets.
