A. 400 gal
B. 500 gal
C. 560 gal
D. 600 gal
B. 500 gal
Surface Area:
800 T × 250 sq ft/T = 200,000 sq ft.

A. $422.50
B. $527.00
C. $687.25
D. $832.50
D. $832.50
$18.50/hr x 1.5 hr = $27.75.
$27.75/hr x 10 hr/worker = $277.50.
$277.50/worker x 3 workers =
$832.50
A crew consists of a foreman ($16.20/hr), three journeymen ($13.50/hr each), and an apprentice ($11.00/hr). The crew works an 8-hour day. What are the total wages?

$16.20 ÷ $13.50 + $13.50 + $13.50
+ $11.00 = $67.70 /hr.
$67.70/hr x 8/hr = $541.60
