Create Equations from Real-Life Algebra Scenarios

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 = 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 apples that John has. If John has y apples, write an equation to express the number of apples Maria has.

• M = 2y + 3

• M = 3y + 2

• M = 2y - 3

• M = y + 3

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

• distance = 60 + t

• distance = 60 - t

• distance = 60t

• distance = 60t^2

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

• z = 25

• z = 30

• z = 35

• z = 45

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 = 2w

• l = w + 2

• l = w - 4

If a book costs $12 and you have a budget of b dollars, how many books can you buy? Create an equation to represent this scenario.

• b / 12

• b * 12

• b - 12

• b + 12

A farmer has 20 apples and gives away x apples. Write an equation to find out how many apples the farmer has left.

• 20 * x

• x - 20

• 20 - x

• 20 + x

The total cost of 5 notebooks and y pens is $25. Write an equation to express the relationship between the notebooks and pens.

• 10x + y = 25

• 3x + 2y = 25

• 5x + 10y = 25

• 5x + yz = 25

A movie theater has x seats. If 75% of the seats are filled, how many seats are occupied? Create an equation to represent the number of occupied seats.

• x + 0.75

• 0.75 * x

• 0.5 * x

• x - 0.25 * x

If the perimeter of a square is p and each side is s, write an equation that relates the perimeter to the side length.

• p = 4s

• p = 2s

• p = 3s

• p = s^2
