Question

Tony bought 3 boxes of 1-inch nails for a total of 237 1-inch nails and 5 boxes of 2-inch nails that had equal amounts of nails. He bought a total of 507 nails. Find the number of nails in each box of 2-inch nails.

Answer 1

Answer: the number of nails in each box of 2-inch nails is 54

Explanation:

Let x represent the number of nails in each box of 2-inch nails.

Tony bought 3 boxes of 1-inch nails for a total of 237 1-inch nails. This means that the number of 1-inch nails in each box is 237/3 = 79

He also bought 5 boxes of 2-inch nails that had equal amounts of nails. He bought a total of 507 nails. This means that

237 + 5x = 507

5x = 507 - 237

5x = 270

x = 270/5

x = 54
