For her cell phone service plan, Angel pays $32 a month plus $0.75 for each minute over the allowed minutes in her plan. Angel received a bill for $47 last month. How many minutes did she go over on her plan?

Jim paid a gym membership fee of $50, plus $20 per month. Jim has paid a total of $290 to the gym. Which equation matches this situation?

• 50 + 20m = 290

• 20 + 50m = 290

• 50 + 20 = m

• 50m - 20 = 290

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

• 7x + 35 = 63

• 7x = 63

• 7x - 35 = 63

• 35x + 7 = 63

-2 = 4r + s

Solve for s.

• s = -2 + 4r

• s = 2 - 4r

• s = -2 - 4r

• s = 2 + 4r

Solve for x:

• x = yb - v

• x = by - v

• x = by + v
