H.W solving Equations

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

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

A banana has 85 calories. This is 10 calories less than one eighth of the calories in a banana split. Which equations helps you find how many calories are in a banana split?

• 85 - 10 = x
• x/8 + 10 = 85
• x/8 - 10 = 85
• x/8 - 10 = 75

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

x + 10 = -30

• x = -20

• x = -40

• x = 20

• x = 3

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

2 (x - 4) =18

• x = 20

• x = 7

• x = 11

• x = 13

3(3x - 6) = 18

• x = 4

• x = -4

• x = 0

• x = -12

• x = 20
• x = 7
• x = 10
• x = 3

What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10
• v + 4 = 10
• 10 - 4 = v
