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 = x + 0.50

• total cost = 0.50 / x

Maria has 3 more than twice the number of apples that John has. If John has y apples, write an equation to express the number of apples Maria has.

• M = 2y - 3

• M = 2y + 3

• M = y + 3

• M = 3y + 2

A car travels at a speed of 60 miles per hour. How far will it travel in t hours? Write an equation to represent the distance traveled.

• distance = 60 - t

• distance = 60 + t

• distance = 60t^2

• distance = 60t

A rectangle has a length that is 4 meters longer than its width. If the width is w meters, write an equation for the length of the rectangle.

• l = w + 4

• l = w + 2

• l = 2w

• l = w - 4

The sum of a number z and 15 is equal to 50. Write an equation to find the value of z.

• 25

• 35

• 45

• 40

A book costs $12. If you buy b books, how much do you pay in total? Write an equation to represent the total cost.

• total cost = 12 - b

• total cost = 12 * b

• total cost = 12 / b

• total cost = 12 + b

The perimeter of a square is 40 meters. If s is the length of one side, write an equation to find the value of s.

• s = 20 meters

• s = 10 meters

• s = 5 meters

• s = 15 meters

A movie ticket costs $8. If you buy m tickets, how much do you spend? Write an equation to represent the total cost of the tickets.

• total cost = 8 * m

• total cost = 8 - m

• total cost = 8 / m

• total cost = 8 + m

A farmer has 20 more chickens than ducks. If d represents the number of ducks, write an equation to express the number of chickens the farmer has.

• c = d - 20

• c = d + 20

• c = d + 10

• c = 2d

The total number of students in a class is 30. If x represents the number of boys, write an equation to find the number of girls in the class.

• girls = 30 - x

• girls = x + 30

• girls = 30 + x

• girls = 30 - 15
