I am pretty sure 52 degrees
The area is the product of length and width, which is to say that the length and width are factors of the area.
Assuming the dimensions are integers, you want factors of 84 that differ by 5.
... 84 = 1×84 = 2×42 = 3×28 = 4×21 = 6×14 = 7×12
The last of these pairs differ by 5, so ...
- the length is 12 inches
- the width is 7 inches.
Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
No, he almost earns $400
9.20 / 1.5 = 6.13
9.20 - 6.13 = 3.07
9.20 + 3.07 = 12.27
12.27 x 2.25 = 27.61
9.20 x 40 = 368
368 + 27.61 = 395.61
Mr. Evans earned $395.61 for 42.25 hrs.
It would fall between 6 and 7.
