Model Two-Step Equations

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 + 5x = 4000

• 800x + 5 = 4000

• 4000 + 5x= 800

• 800 + 5 = 4000

Mr. Piper's plumbing needed repairs. The plumber charged $98 for parts plus $45 per hour for labor. If the bill totaled $458, how could I find out the hours of labored required?

• 98x + 45 = 458

• 98 + 45x = 458

• 45 + 98 = 458

• 45x - 98 = 458

The 30 members of a choir are trying to raise $1500 to cover travel costs to a singing 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?

• 30x + 600 = 1500

• 30x - 600 = 1500

• x + 600 = 1500

• 30x = 1500
