Creating Equations Based on Word Problems

Cadin rents a bouncy house for a birthday party. It costs $30.00 plus $4.00 per hour. If he spends a total of $78.00, how many hours did he keep the bouncy house?

• $30.00 - $78.00 = $4.00h

• $78.00 + $30.00 = $4.00h

• $30.00 + $4.00h = $78.00

• $30.00 - $4.00h = $78.00

Lisa is cooking muffins. The recipe calls for 7 cups of sugar. She has already put in 2 cups. How many more cups does she need to put in?

• 2 + n = 7

• n - 7 = 2

• 2 - n = 7

• 7 + n = 2

After paying $5.12 for a salad, Daxton has $27.10. How much money did he have before buying the salad?

• n + $5.12 = $27.10

• n - $5.12 = $27.10

• n - $5.12 = $27.10

• $5.12 - n = $27.10

Emily earns $14 per hour. Which equation represents how many hours she worked to earn $112? 

• 14h = 112

• h + 14 = 112

• 14 / h = 112

• h - 14 = 112

Robyn had some video games then bought 4 more.  Now she has a total of 10 games.  (Remember you are in 7th grade, not 1st grade)

• v - 4 = 10

• v + 4 = 10

• 10 - 4 = v

• 10 + 4 = v
