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 = 2 + x

• total cost = x + 2

Maria has 5 more than twice the number of books that John has. If John has y books, express the number of books Maria has in an equation.

• 2y + 5

• 3y + 2

• y + 5

• 2y - 5

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

• distance = 60 + t

• distance = 60t

• distance = 60t^2

• distance = 30t

The sum of a number z and 12 is equal to 30. Write the equation that represents this situation.

• 12z = 30

• z + 12 = 30

• z - 12 = 30

• z + 12 = 20

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

• flour = 4s

• flour = 2s

• flour = (3/2) * s

• flour = s/2

If a rectangle has a length of l meters and a width of 4 meters, what is the formula for the area of the rectangle? Write the equation for the area.

• A = l + 4

• A = 4l

• A = 2l

• A = 4l^2

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

• total_cost = 10 * n

• total_cost = 10 - n

• total_cost = 10 + n

• total_cost = n / 10

The perimeter of a square is 4 times the length of one side. If the length of one side is s, write the equation for the perimeter.

• P = 2s

• P = s + s + s + s

• P = 4s

• P = 8s

A gardener plants x flowers in each row. If there are 5 rows, how many flowers are planted in total? Write the equation for the total number of flowers.

• 5 + 5 * x

• x * 5 + 5

• x + 5

• 5 * x

If you have 15 apples and you give away a number a of apples, how many apples do you have left? Write the equation for the remaining apples.

• 15 - 15

• 15 - a

• a - 15

• 15 + a
