Let c be crayons, and p be paper.
1c + 5p = $54
5c + 3p = $50
Solve these equations for c and p.
22p = $220
So p = $10.
Put this into one of the equations, and solve to find that c = $4
$4 per box of crayons, and $10 per ream of paper.
Step-by-step explanation:
perimeter = 2(length) + 2(width)
let x represent the width of the rectangle




therefore width = 3 cm
length = 3+9
= 12cm
