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

Equation 1

18 represents the number of tickets Zhi starts with. -3 is how many tickets each game uses, G is the amount of games played.

Equation 2

This equation is just equation 1 in factored form, 3 times 6= 18 and -g times 3= -3g. All of the parts are the same from the first equation.

Hope this helps some!!
