Casper bought some pencils at \$.50 each. He had \$3 left after the purchase. If he wanted to buy the same number of note pads at \$.80 each, he would be short \$1.50. Write a linear equation for the number of pencils he purchased. Then solve it.

• Math -

.50p+3 = .80p-1.50
.3p = 4.50
p = 15

so, 15 pencils cost \$7.50, meaning he started out with \$10.50
15 notepads cost \$12.00, so he'd be \$1.50 short.
