• -50

Where/what is the mistake?

• Line 2 - You should add 12 to both sides.

• Line 4 - You should divide both sides by 2/3.

• Line 4 - You should multiply both sides by the original fraction.

• Line 5 - There was a calculation error.

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 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63
