Question

jose had $26 to spend on school supplies. After buying 10 pens, he had $14.30 left. Write an equation you could use to fund how much each pen cost?

Answer 1

Let the price of a pen be x.

We have an equation:
10*x+ 14.30= 26
⇒ 10x= 26- 14.30
⇒ 10x= 11.7
⇒ x= 11.7/10
⇒ x= 1.17

Each pen costs $1.17~
