Real World Problem Equations

Becky is preparing for her younger sister's birthday party. She splits a jar of lollilops evenly among 6 goody bags. Each bag ends up with 4 lollipops. Which equation can you use to find the number of lollipops n in the jar?

• n/6 = 4

• n - 4 = 6

• 4n = 6

• n + 6 = 4

Charlie has some candy. He shares ten pieces with Betsy and is left with 24 pieces. Which equation should I use to solve this problem?

• x +10 = 24

• x - 10 = 24

• 10x = 24

• x + 24 = 10

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.

• h = 2C + 15

• C = 15h + 2

• h = 15C + 2

• C = 2h + 15

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of airtime usage.  If Juanita uses x minutes of airtime, what is an equation that can be used to determine her monthly cell phone bill (C)?

• C = 15 + 0.20x

• C =15 (0.20x)

• C = 15 + x + 0.20

• C = 0.20 + 15x

Which choice models this situation? Chris has read 125 pages in a book. The book has a total of 262 pages. How many pages does she have left to read to finish the book?

Sarojini is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she spends $35 in all.

• .50x + 20 = 35

• .50x = 35

• .50 + 20x = 35 

• .50x - 20 = 35

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

• 7x + 35 = 63

• 7x = 63

• 7x - 35 = 63

• 35x + 7 = 63

An Uber charges $3, plus $1.50 for each mile traveled.  Sam rode in the Uber from their home to the airport and was charged $30.  How many miles does Sam live from the airport?

WRITE AN EQUATION Harper had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

• 24-10=7x

• 24+7x=10

• 10+7x=24

• 10+x=14

WRITE AN EQUATION
Aiyana had some candy to give to her four cousins. She first took ten pieces for herself and then evenly divided the rest among her cousins. Each child received two pieces. Write the equation to solve this question correctly.

• (x-10)/4=2

• x-10/4=2

• x-10=2(4)

• 2(x-10)=4
