An employment agency specializing in temporary construction pays heavy equipment operators $138 per day and general laborers $87 per day. if thirty-three people were hired and the payroll is $4044? how many heavy equipment operators were employed? how many laborers were employed?

L = 2,

O = 31

Step-by-step explanation:

First using the givens, write out some formulas.

Heavy equipment operators = O

General laborers = L

Now use substitution, it doesn't matter which one you substitute.

Distribute and solve for L.

L = 2, meaning number of laborers employed is 2.

Now plug 2 = L into one of the original equations.

O = 31, meaning number of heavy equip. operators employed is 31.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
