Question

A student bought 1 box of crayons and five reams of paper for $54 she bought five boxes of crayons and three 3 reams of paper for $50 what is the cost of each box of crayons and each reams of paper

Answer 1

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.
