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.
8x-10=3x+90. 8x-3x=90-10. 5x=80. x=16. So angle B is 3*16+90=138° :)
