p ≥ ?

-------------------------------------------------------------------

A painter earns $15 an hour. What is the minimum number of hours he must work to earn at least $200? Write an inequality to represent this situation and solve.

A- 15h ≥ 200; h ≥
`13 (1)/(3)`
B- 15h ≤ 200; h ≤
`13 (1)/(3)`
C- 200h ≥ 15; h ≥
`(3)/(40)`
D- 200h ≤ 15; h ≤
`(3)/(40)`

Answer 1

The first is 40.
The second is A.

Answer 2

For the first one, you want to divide 200 by 5 since you want to find an arrange for each day. She should read on average 40 pages a day. For part B, I think A represents it because they average $15 an hour, which 15h represents. It has to be greater or equal to 13.3 because that is the minimum that is closest to $200 if you round it up.
