Only your first answer is right.
1. Yep
2. You would have to multiply 15% by 38, because it's asking for the number of students who did NOT pass their test.
38 * 0.15 = 5.7 or approximately equal to 6 students
3. Let n be the sales price
It was said that 52% or 0.52 of the sales price is the profit. Thus,
0.52 * n = 2000
n = 2000 / 0.52
n = $ 3846.15
4. Percent Markup is the increase on the original selling price. To find it, we divide the selling price by the original, then we subtract 1:
(32.95 / 11.1) - 1
2.968 - 1
1.968
In percent, 1.968 * 100 = 196.8 %
Hope this helps :3
