Answer:
16 tons
$9108
Explanation:
Let t = number of tons.
First company:
cost = 100.5t + 7500
Second company:
cost = 175.75t + 6296
At what number of tons are the costs equal?
We set the two cost equations equal and solve for t.
175.75t + 6296 = 100.5t + 7500
75.25t = 1204
t = 16
The costs are equal for 16 tons.
The cost for 16 tons is:
cost = 100.5t + 7500
cost = 100.5(16) + 7500
cost = 9108
At 16 tons, the cost is $9108
