She pays 40% so 3292 times by 0.40 gives you 1,316.80 is what she pays.
The scale factor used is .5 because 7, 8, and 10 multiplied by .5 will equal 3.5, 4, and 5.
190 / 40 = $4.75 an hour
4.75 • 60 = 285
At the same rate, he should be paid<span> $285</span> for 60 hours of work
1. 1/a^8 (Sorry I can't find out what the others are)
1 ft = 12 in
6 in = 6/12 = 0.5 ft
9 in = 9/12 = 0.75 ft
D = M/V ⇒ M = DV
V = 0.5 * 0.5 * 0.75 = 0.1875 cubic foot
M = 41.7 * 0.1875 ≈ 7.8 pounds
Answer: B.
