Question

Zhi bought 18 tickets for games at a fair. Each game requires 3 tickets. Zhi wrote the expression 18 – 3g to find the number of tickets she has left after playing g games. Diego correctly wrote another expression, 3(6 – g), that will also find the number of tickets Zhi has left after playing g games. Use the drop-down menus to explain what each part of Zhi's and Diego's expressions mean.

Answer 1

Yes, Zhi's expression multiplies the tickets per game by the number of games to get the number of tickets used and then subtracts this amount from the total tickets.

Answer 2

3- The number of tickets each game requires.
18 - The number of tickets bought.
g - The number of games played.

The "3g" represents the number of games we can determine Zhi and Diego went to. Both equations have values and variables that mean the same thing, however Diego chose to use the distributive property in setting up his equation.
