Question

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

Answer 1

Answer:

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
