Solving for a Variable Practice

If one roll of masking tape costs $1.15, how many rolls can Emma buy with $5.75?

• 1.15(5.75) = x

• 5.75x = 1.15

• 1.15x = 5.75

• x = 1.15/5.75

WRITE AN EQUATION
You bought a magazine for $5 and four
erasers. You spent a total of $29. How
much did each eraser cost?

• 5 + x = 29

• -5 - 4x = -29

• 5x = 29

• 29 - 5 = -4x
