Amy purchased 17 pencils and 18 pens for a fund-raiser at school and spent $61.50. Jocelyn purchased 10 pencils and 21 pens and spent $57. How much does each pencil cost?

Write a equation system: 17x+18y=61.5
10x+21y=57
Where x is cost per each pencil purchased and y is cost of each pen purchased. So you have to solve this system and get x=1.5 and y=2
