Jazmine joined a music club.  The start up fee was $10.00.  Each song she downloads is $0.99.  If she spent a total of $15.94, how many songs did she download?

• $10.00 + $0.99m = $15.94
• $10.00m + $0.99 = $15.94
• $10.00/$0.99m = $15.94
• $10.00 - $0.99m = $15.94

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

A taxi charges $3, plus $1.50 for each mile traveled.  Mr. Lewis rode in the taxi from his home to the airport and was charged $30.  Which equation can be used to find how many miles Mr. Lewis lives from the airport?

• 3x + 30 = 1.50

• 1.50x + 3 = 30

• 30x + 1.50 = 3

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63
• 7x = 63
• 7x - 35 = 63
• 35x + 7 = 63

472 students are going on a field trip. 120 students will be returning home and the rest will be spending the night in cabins. If a cabin sleeps 8 people, which equation can be solved to find how many cabins need to be rented?

• 120 - 8c = 472

• 120 + 8c = 472

• 120c - 8 = 472

• 120c + 8 = 472

Maria has 25 dollars.  She has to buy a gallon of milk which costs $3.50.  She wants to spend the rest of her money on cereal that costs $4.50 per box. Which equation can be used to find out how many boxes she can purchase?

• 3.50x + 4.50 = 25

• 3.50x + 25 = 4.50

• 4.50x + 3.50 = 25

• 4.50x + 25 = 3.50

A toy company spends $1500 per day for factory expenses plus $8 to make each teddy bear.  They spent $12,000 one day.  Which equation could be used to find the number of bears t the company has made that day?

• 1500 + 8t = 12000

• 12000 + 8t = 1500

• 1500 - 8t = 12000

• 8t - 12000 = 1500

A fitness club opens with 80 members. Each month the membership increases by 15 members. Which equation represents the relationship between the number of months the club has been opened, x, and the total fitness club membership, y?

• y=15x
• y=15x+80
• y=x+15
• y=80x+15

Sandra has a $20 itunes gift card and spends $3 each month.  Which equation can be used to find how much money Sandra has on her giftcard after x months?

• y = 3x + 20
• y = 3 + 20x
• y = -3x + 20
• y = -20x + 3

Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour of use to rent a paddle boat.  Write an equation for C, the total cost, to rent the boat for h hours.
