Lesson 16- Writing Two-Step Equations

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

• 290m- 50 = 20

The perimeter of a rectangle is 54 cm. Its length is 6cm. What is the width of the rectangle?

• 6 + x = 54

• 2(6 + x) = 54

• 6x = 54

Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she spends $35 in all.

• 35r + 0.50 = 20

• 20r + 0.50 = 35

• 20 + 0.50r = 35

The 30 members of a choir are trying to raise $1500 to cover travel costs to a signing camp. They have already raised $600. Which equation would you solve to find the average amount each member can raise in order to meet the goal?

• 30m - 600 = 1500

• 600 + 30m = 1500

• 600m + 30 = 1500

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.

• 15 + 2 = 33h

• 15h + 2 = 33

• 15 + 2h = 33

Pizzazz 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 + 5b = 4,000

• 800 - 5b = 4,000

• 800b + 5 = 4,000
