$3,000

Explanation:

Given that

Selling price of each skateboard = $4

The expenses are

Wheels = $3

Plastic board = $1

Paint = $1

Labor = $10

So, the total expenses per unit is = $15

So, the profit is

= Selling price per skate board × number of units sold - expenses per unit  × number of units sold

= $45 × 100 - $15 × 100

= $4,500 - $1,500

= $3,000
