To find the ink cost of each card coming from printer B, we need to find the total cost from printer B and the total number of cards printed by Printer B.
The total hours of all the three printers over the three weeks

The total hours of printer B only

Total number of cards produced over the three weeks

We can use ratio and proportion to determine the total cards produce by printer B only.

divide by 8
x=20
The answer is A. -∞ < y < 2
There are 3 types of cost for this problem: the cost for the area covered by the tiles, cost for hourly labor and the sales tax.
Cost of Area = (10.5 ft)(8 ft)($4.75) = $399
Cost of Hourly Labor = ($22/h)(7.5 h) = $165
Sum = $399 + $165 = $564
Cost of tax = $564(0.08) = $45.12
Total Cost = $564 + $45.12 = <em>$609.12</em>
So, the amount of the bill is incorrect.
