Kathryn bought a magazine for $4 and five erasers. She spent a total of $14. How much did each eraser cost?

Each eraser costs $2.00

Step-by-step explanation:

Step 1: Make an equation

4 + 5a = 14

4 = shows that cost for one magazine

5a = shows that 5 erasers cost a each

14 = total price

Step 2: Solve for a

Subtract 4 from both sides: 4 + 5a - 4 = 14 - 4

Divide by 5 from both sides: 5a / 5 = 10 / 5

Answer: a = 2
