Question 5 • Grade 7 Mathematics

On Friday, there were x students at the baseball game. On Monday, there were half as many students at the game as there were on Friday. On Wednesday, there were 32 fewer students at the game as there were on Friday. Which expression could represent the total number of tickets sold for all 3 games?

Answer
A
3 and 1 half x plus 32
B
2 and 1 half x minus 32
C
3 and 1 half x minus 32
D
2 and 1 half x plus 32

Explanation

Friday’s game had x students. Monday’s game had half as many, or x/2, and Wednesday’s game had x − 32. Adding the three amounts gives x + x/2 + (x − 32) = 2.5x − 32, which is choice B, “2 and 1 half x minus 32.”
