Word question consisting of two pack

Question

You purchase 2 pencils packs and 3 highlighter packs which equals $8.25. You friend purchases 5 pencil packs and 2 highlighter packs for $11. Solve how much each pack is.

Answer 1

2P + 3H = 8.25

5P + 2H = 11

 

from equation 1

P = 4.125 - 1.5H

substitute in equation 2

5 (4.125 - 1.5H) + 2H = 11

-5.5H  = 11 - 20.625

H = $1.75

P = 4.125 - 1.5H = $1.5
