This morning, the temperature was 80 ⁰F. It dropped 5 degrees per hour. In how many (h) hours did the temperature drop to at most 40 ⁰F? Using the inequality 80 - 5h ≤ 40, which solution makes sense?
a. h ≥ 8 (The temperature dropped for more than 8 hours.)
Selected:b. h ≤ 8 (The temperature dropped for 8 hours or less.)This answer is incorrect.
c. h ≥ 8 (The temperature dropped for 8 hours or more.)
d. h ≤ 8 (The temperature dropped for less than 8 hours.)
