Algebra practice question
A tutor charges $25 per hour. Priya has at most $180 to spend on tutoring this month. Which inequality gives the possible numbers of hours h she can book?
- A. 25h ≤ 180Correct
- B. 25h ≥ 180
- C. h ≤ 180 + 25
- D. 25 + h ≤ 180
Answer: A. 25h ≤ 180
h hours cost 25h, which must not exceed 180.
Why the other answers are wrong
- B. 25h ≥ 180
- This requires spending at least $180.
- C. h ≤ 180 + 25
- This adds the rate to the budget.
- D. 25 + h ≤ 180
- This adds one hour's charge to the count of hours.
