Answer:
Total cost= $51
Step-by-step explanation:
<u>Giving the following information: </u>
Fixed cost= $5
From 0 to 40,000 gallons= $0.0007 per gallon
From 40,001 to infinity= $0.0009
<u>We need to calculate the total cost for 60,000 gallons:</u>
Total cost= 5 + 40,000*0.0007 + 20,000*0.0009
Total cost= $51
-5x + 46 +4z
Combine like terms
-5x + 2x = -3x
-3x + -2x = -5x
14 - (-32) = 46
4z is left alone since it doesn't have a like term.
