Translate Real-Life Scenarios to Linear Equations

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

• total cost = 0.50 - x

• total cost = 0.50 / x

• total cost = 0.50 * x

• total cost = x + 0.50

Maria has $20. She spends x dollars on a book. Write an equation to find out how much money she has left.

• 20 + x

• x - 20

• 20 * x

• 20 - x

A car rental company charges a flat fee of $30 plus $0.20 per mile driven. If you drive x miles, write an equation for the total cost of the rental.

• Total Cost = 30 + 0.20 * x

• Total Cost = 30 + 0.20 * (x + 10)

• Total Cost = 30 + 0.50 * x

• Total Cost = 30 - 0.20 * x

John is saving money to buy a video game that costs $60. If he saves x dollars each week, how many weeks will it take him to save enough? Write an equation to represent this situation.

• weeks = 60 + x

• weeks = 60 - x

• weeks = 60 * x

• weeks = 60 / x

A gardener plants x flowers in a row. If each row has 5 flowers, how many flowers are there in total? Write an equation to express this relationship.

• total_flowers = 5 - x

• total_flowers = 5 * x

• total_flowers = 5 / x

• total_flowers = x + 5

A school is organizing a field trip. Each student pays $15. If there are x students, write an equation to find the total amount collected for the trip.

• total_amount = x + 15

• total_amount = 15 * x

• total_amount = 15 / x

• total_amount = 15 - x

A recipe requires 2 cups of flour for every x cookies made. If you want to make 24 cookies, how many cups of flour do you need? Write an equation to solve this problem.

• 2 cups

• 4 cups

• 3 cups

• 1 cup

A phone plan costs $25 per month plus $0.10 per text message sent. If you send x text messages, write an equation for the total monthly cost.

• Total Cost = 25 * x + 0.10

• Total Cost = 25 + 0.10 * x

• Total Cost = 0.10 + 25 * x

• Total Cost = 25 + 0.10 * (x + 1)

Samantha is reading a book that has 300 pages. If she reads x pages each day, how many days will it take her to finish the book? Write an equation to represent this situation.

• days = 300 * x

• days = x - 300

• days = 300 / x

• days = 300 + x

A concert ticket costs $50. If you buy x tickets, how much do you spend in total? Write an equation to express the total cost.

• total cost = 50 * x

• total cost = 50 / x

• total cost = 50 - x

• total cost = 50 + x
