Equation to Fit Word Problem

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

A group of 3 friends each have video games at their home.  Then each friend buys 5 more video games.  Now the three friends have a total of 30 video games.  How many video games did each friend start with?

• 3(x+5) = 30

• x(3+5) = 30

• 5(x+3) = 30

• 30(3+5) = x

Last season, I spent $2752 to see my team play 43 games.  To see each game, I had to buy a ticket and pay $10 for parking.  How much was each ticket?

• 10(x+43) = 2752

• x(10+43) = 2752

• 43(x+10) = 2752

• 2752(43+x)=10

You mailed 20 identical Christmas cards weighing more than 1 ounce each.  Mailing each card costs $.44 for the first ounce, plus .17 for each additional ounce.  The postage for all cards totalled $15.60.

• 20(.17w) = 15.60

• 20(.44w) = 15.60

• 20(.17w + .44) = 15.60

• 20(.44w + .17) = 15.60

You take out a loan from a bank for $3600.  You plan to pay back 300 per week.  Which equation would help you solve the number of weeks to pay back the loan?

• 3600 - 300w = 0

• -3600w + 300 = 0

• 0 - 3600 = 300w

• w + 3600 + 300 = 0

Four friends bought pizza.  They all split the cost evenly.  The pizza was $16.00.  The total bill came to $32.00.  Which equation matches this story.

• 4 + 16 = 32

• 16-4 = 32x

• 16 + 4p = 32

• 4p + 16 = 32
