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

• total cost = x + 0.50

• total cost = 0.50 + x

• total cost = 0.50 * x

• total cost = 0.50 / x

Maria has 3 more than twice the number of books that John has. If John has x books, write an equation to represent the number of books Maria has.

• 3x + 2

• 2x + 3

• 2x - 3

• x + 3

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

• Total Cost = 20 - 0.15m

• Total Cost = 0.15m

• Total Cost = 20 + 0.15m

• Total Cost = 20 + 0.10m

Tom is 4 years older than his sister. If his sister is x years old, write an equation to express Tom's age.

• Tom's age = x + 4

• Tom's age = x - 4

• Tom's age = 4 - x

• Tom's age = x + 2

A recipe requires 2 cups of flour for every 3 cups of sugar. If you have y cups of sugar, write an equation to find the amount of flour needed.

• x = y/3

• x = (2/3)y

• x = 3y

• x = (3/2)y

A concert ticket costs $30, and you have $x. Write an equation to find out how many tickets you can buy.

• x + 30

• x / 30

• x * 30

• 30 - x

The length of a rectangle is 5 meters more than its width. If the width is w meters, write an equation for the length of the rectangle.

• l = 5w

• l = w + 10

• l = w + 5

• l = w - 5

A swimming pool is being filled at a rate of 2 gallons per minute. If it starts with g gallons, write an equation for the total gallons after t minutes.

• g + 2t

• g + t

• g - 2t

• 2g + 2t

A farmer has 50 apples and wants to distribute them equally among x baskets. Write an equation to find out how many apples will be in each basket.

• 50 * x

• 50 - x

• 50 + x

• 50 / x

A book costs $15, and you want to buy y books. Write an equation to find the total cost of the books.

• total_cost = 15 / y

• total_cost = 15 * y

• total_cost = y - 15

• total_cost = 15 + y
