Algebra practice question
A bakery sells loaves for $4 each and rolls for $1 each. On one day it sold three times as many rolls as loaves, taking $84 in total. How many loaves did it sell?
Answer: 12
Let L be the loaves; rolls = 3L. Revenue: 4L + 1(3L) = 7L = 84 → L = 12.
Common wrong answers
- If you answered 21
- 21 comes from 4L = 84, ignoring the rolls.
- If you answered 28
- 28 comes from 3L = 84, counting only the rolls.
- If you answered 36
- 36 is the number of rolls.
