1. Lighting Fixtures

An apprentice unpacked 12 dozen fragile lighting fixtures. He was to receive $3 for each fixture that he unpacked safely and he agreed to pay$25 for every one that he broke. If the amount due him for his work was \$236, how many did he break?

2. Re :

I got 2 equations here .
Let x be the number of successful lightning fixtures
Let y be the number of broken lightning fixtures .

12 dozen = 144

$x+y=144$ ---- 1
$3x-25y=236$ ------ 2

Solve for y ..

I can take it from here.
