Jim paid a gym membership fee of $50, plus $20 per month.  Jim has paid a total of $290 to the gym.  How many months has Jim been a member of the gym?

• 50 + 20m = 290

• 20 + 50m = 290

• 50 + 20 = m

• 50m - 20 = 290

Mr Carrillo's family bought lunch from Culvers. They also bought some sodas from Quick Trip for $5.00. The meals cost $6.00 each. The total cost of the lunch and soda was $41.00. Let x represent the cost of the number of meals that Mr. Carrillo bought. Write the equation and solve for x.

• -5+6x = 41, 4 meals

• 6x + 5 = 41, 6 meals

• 6x = 36 meals

• 5 + 6x = 41, 7 meals

An electrician charges $90 per hour plus a $50 travelling fee. It costs $1000 in total.

• 1000 = 50x + 90

• 1000 = 90x + 50

• 90 = 1000 + 50x

• 90x = 1000 + 50

• 50 = 90x + 1000

Harris Publications is having some books printed. The printer charges $800 plus $5 per book. What equation could help me find how many books can be printed for $4,000?

• 800 + 5x = 4000

• 800x + 5 = 4000

• 4000 + 5x= 800

• 800 + 5 = 4000

• 4000 = 800 + 5

Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour of use to rent a paddle boat.  Write an equation to find out how many hours, h, they rented the Boat if the total cost was $33.

• h = 2(9) + 15

• 33 = 15h + 2

• h = 15(9) + 2

• 33 = 2h + 15
