Translate Everyday Scenarios into Linear Equations

A store sells pencils for $0.50 each. If you buy x pencils, how much will you spend? Write an equation to represent the total cost.

• total cost = 1.00 * x

• total cost = 0.25 * x

• total cost = 0.50 * x

• total cost = x + 0.50

Maria has 3 times as many marbles as John. If John has y marbles, how many does Maria have? Write an equation to express this relationship.

• 3y

• 4y

• y

• 2y

A car rental company charges a flat fee of $20 plus $0.15 per mile driven. If you drive m miles, how much will you pay? Write an equation for the total cost.

• C = 20 + 0.15m

• C = 20 - 0.15m

• C = 0.15m - 20

• C = 20 + 0.50m

A gardener plants x flowers in each row. If there are 5 rows, how many flowers are planted in total? Write an equation to represent the total number of flowers.

• 10x

• 5+x

• 5x

• x+5

Tom is saving money to buy a video game that costs $60. If he saves $5 each week, how many weeks will it take him to save enough? Write an equation to find the number of weeks.

• 12 weeks

• 15 weeks

• 10 weeks

• 8 weeks

A recipe requires 2 cups of flour for every batch of cookies. If you want to make b batches, how many cups of flour do you need? Write an equation to represent this.

• total flour = 2 * b

• total flour = 2 / b

• total flour = 2 - b

• total flour = b + 2

A school is selling tickets for a play. Each ticket costs $8. If they sell t tickets, how much money do they make? Write an equation for the total revenue from ticket sales.

• R = 5t

• R = 8t

• R = 10t

• R = 8 + t

Lisa has $50 and spends $10 each week. How many weeks can she continue to spend this amount before running out of money? Write an equation to find the number of weeks.

• 10 weeks

• 3 weeks

• 7 weeks

• 5 weeks

A train travels at a speed of 60 miles per hour. If it travels for h hours, how far does it go? Write an equation to express the distance traveled.

• distance = h/60

• distance = 60h^2

• distance = 60 + h

• distance = 60h

A phone plan costs $30 per month plus $0.10 per text message. If you send m messages, how much will your bill be? Write an equation for the total monthly cost.

• Total Cost = 30 * m + 0.10

• Total Cost = 30 - 0.10 * m

• Total Cost = 30 + 0.10 * m

• Total Cost = 30 + 0.10 + m
