Jim paid a gym membership fee of $50, plus $20 per month. Jim has paid a total of $290 to the gym. Which equation could be used to find m, the number of months Jim has been a member of the gym?

• 50 + 20m = 290

• 20 + 50m = 290

• 50 + 20 = m

• 50m - 20 = 290

While at the music store, Drew bought 5 CDs, all at the same price. The tax on his purchase was $6, and the total was $61. Which equation can be used to find x, the price of each CD?

• 5x + 6 = 61

• x/5 + 6 = 61

• 5/x + 6 = 61

• x + 5 + 6 = 61

A computer printer can print 10 pages per minute. There were already 35 pages in the tray. The total pages printed was 115 pages. Write an expression for the number of pages the printer can print in m minutes.

• 10m + 35 = 115

• 10m + 115 = 35

• 115m + 35 = 10

• 35m + 10 = 115

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63

• 7x = 63

A plumber charges $50 to make a house call plus $40 for each hour worked. What is the equation that can be used to find the number of hours he worked if he made $250?

• 50x + 40=250

• 50x + 40x=250

• 50 + 40x=250

• 90x=250

Mallory bought pizza and soda for her End of Summer party. If she spent $12.57 on the sodas and $10.95 for each pizza, how many pizzas did she buy if she spent $89.22? Which equation models this scenario?

• 10.95x + 12.57 = 89.22

• 89.22x - 10.95 = 12.57

• 12.57x + 10.95 = 89.22

• 12.57 + 10.95 = 89.22
