Solving and Graphing Linear Equations in Real-World Scenarios

1. A car rental company charges a flat fee of $50 plus $0.20 per mile driven. Write the equation for the total cost (C) in terms of miles driven (m). If another company charges $30 plus $0.25 per mile, write the equation for their total cost. How many miles must you drive for both companies to charge the same amount?

• 350 miles

• 600 miles

• 200 miles

• 400 miles

2. Sarah and Tom are selling lemonade. Sarah sells her lemonade for $2 per cup, while Tom sells his for $1.50 per cup. Write the equations for their total earnings (E) based on the number of cups sold (c). How many cups must each sell for their earnings to be equal?

• They must sell 1 cup for their earnings to be equal.

• They must sell 4 cups for their earnings to be equal.

• They must sell 2 cups for their earnings to be equal.

• They must sell 0 cups for their earnings to be equal.

4. A school is planning a field trip. The cost per student is $15 for the bus and $5 for admission. Another option is a $10 bus fee and $10 admission. Write the equations for the total cost (C) based on the number of students (s). How many students must attend for both options to cost the same?

• Both options are only equal when there are 5 students.

• Any number of students (both options cost the same for all s)

• At least 10 students must attend for both options to cost the same.

• The first option is cheaper for any number of students.

7. A farmer sells apples for $1.50 per pound and oranges for $2 per pound. If he sells a total of 50 pounds of fruit for $90, write a system of equations to find out how many pounds of each fruit he sold.

• x + y = 40, 1.5x + 2y = 80

• x + y = 60, 1.5x + 2y = 100

• x + y = 50, 1.5x + 2y = 90

• x + y = 50, 1.5x + 2y = 70

8. A concert venue has two pricing options for tickets. The first option is $50 per ticket, and the second option is $40 plus a $10 service fee. Write the equations for the total cost (C) based on the number of tickets (t). How many tickets must you buy for both options to cost the same?

• 2

• 5

• 3

• 1

9. A bookstore sells novels for $12 each and textbooks for $25 each. If a customer buys a total of 8 books and spends $156, write a system of equations to determine how many novels and textbooks were purchased.

• x + y = 10, 12x + 25y = 150

• x + y = 7, 12x + 25y = 160

• x + y = 8, 12x + 20y = 156

• x + y = 8, 12x + 25y = 156

• 3.5 miles

• 2 miles

• 5 miles

• 4 miles
