Ray has $36 to buy masonry nails and finishing nails for his project. Masonry nails sell for $5.50 per box, and finishing nails cost $3.50 per box. Only full boxes are available for purchase. If Ray buys 3 boxes of masonry nails, what is the maximum number of boxes of finishing nails he can buy?

6

Explanation:

$5.50 × 3= $16.5 for 3 boxes of masonry nails

$36 - $16.5 = $19.5 left over

$19.5 ÷ $3.50 = 5.571428571
