How I was taught: Make sure both numbers are a fraction. If not put "1" as the denominator. Multiply straight across. Simplify if you can.
Answer:

Answer:
Number of heavy equipment operators hired were 22
Number of general laborers hired were 11
Explanation:
Assume that number of heavy equipment operators hired is x and that number of general laborers is y.
We are given that:
1- Total number of hired people is 33. This means that:
x + y = 33
This can be rewritten as:
x = 33 - y ...........> equation I
2- heavy equipment operators are paid $135, general laborers are paid $89 and that the total payment was $3949. This means that:
135x + 89y = 3949 ............> equation II
Substitute with equation I in equation II and solve for y as follows:
135x + 89y = 3949
135(33-y) + 89y = 3949
4455 - 135y + 89y = 3949
506 = 46y
y = 506 / 46
y = 11
Substitute with y in equation I to get the value of x as follows:
x = 33 - y
x = 33 - 11
x = 22

Answer:
The profit per year will be $23916
Step-by-step explanation:
Cost price of 1 ft³ = $2.05
Selling price of 1 ft³ = $21.98
Profit = Selling price - cost price
profit = $21.98 - $2.05
Profit = $19.93
Profit on 1 ft³ is $19.93
If they sell 100 monthly, per year (12 months), profit will be
19.93*100*12
= $23916
