A store sells pencils for $2 each. If you buy x pencils, how much do you spend? Write the equation for the total cost.

• total cost = 2 + x

• total cost = 2 - x

• total cost = x + 2

• total cost = 2 * x

Maria has 5 more than twice the number of apples that John has. If John has y apples, write an equation to represent the number of apples Maria has.

• M = y + 5

• M = 3y + 5

• M = 2y + 5

• M = 2y - 5

A car travels at a speed of 60 miles per hour. If it travels for t hours, how far does it go? Write the equation for the distance traveled.

• distance = 60t

• distance = 30t

• distance = 60 + t

• distance = 60t^2

Liam has $50. He spends $x on a video game. Write an equation to find out how much money he has left.

• x - 50

• 50 - 50

• 50 - x

• 50 + x

A recipe requires 3 cups of flour for every 2 cups of sugar. If you use y cups of sugar, how many cups of flour do you need? Write the equation for the flour needed.

• flour = (2/3) * y

• flour = (3/2) * y

• flour = (4/3) * y

• flour = 2 * y

A gardener plants x trees in a row. If each tree is 3 feet apart, how long is the row? Write the equation for the total length of the row.

• Length = x * 3

• Length = (x - 1) * 3

• Length = (x - 2) * 3

• Length = (x + 1) * 3

Samantha reads 20 pages of a book each day. If she reads for d days, how many pages does she read in total? Write the equation for the total pages read.

• 10 * d

• 20 + d

• 20 * d

• d - 20

A movie ticket costs $10. If you buy z tickets, how much do you spend? Write the equation for the total cost of the tickets.

• total_cost = 10 / z

• total_cost = 10 - z

• total_cost = z + 10

• total_cost = 10 * z

A bike costs $150. If you save $x each week, how many weeks will it take to buy the bike? Write the equation for the number of weeks needed.

• weeks = 150 * x

• weeks = 150 + x

• weeks = 150 / x

• weeks = 150 - x

A pool can be filled with water in 4 hours. If it is filled at a rate of y gallons per hour, how many gallons does the pool hold? Write the equation for the total gallons.

• 2y

• y gallons

• 4y

• 8y
