Basic Pay = $40
Commission for 1 pair of shoes = $4.50
Let x be the number of shoes he needs to sell.
40 + 4.5x ≥ 112
4.5x ≥ 72
x ≥ 16
Answer: He must sell at least 16 pairs of shoes.
(I'm going to use brackets as my absolute value bars lol)
[5 x -3]
[-15]
=15
26 is a part of the whole. the proportion should be set up:
(26/x) = (5/100) It's the overall enrollment that is being asked.
If you also need to solve: Cross multiply, 26(100) = 5x, 2600 = 5x, divide both sides by 5, 520 is the enrollment
The answer would be 314.16 square cm
Hope this helps! :)
