Algebra practice question

Answer: 7

6k < 45 gives k < 7.5, so the greatest integer is 7.

Common wrong answers

If you answered 8

k = 8 gives 53, which is not less than 50.

If you answered 45

45 is 6k's bound; divide by 6 and take the greatest integer below 7.5.

If you answered 7.5

7.5 is the exact bound; the greatest integer below it is 7.
