Question

School yearbooks cost $23. Fifty-six yearbooks have already been sold. How many more yearbooks x must be sold to earn at least $2001? Write your answer as an inequality.

Answer 1

x
`\geq` 31

Explanation:

Total number of the yearbooks is 56 + x

Total money earned is 23*(56 + x)

so 23*(56 + x)
`\geq` 2001

56 + x
`\geq` 2001/23 = 87

x
`\geq` 87 - 56 = 31

Answer: x
`\geq` 31
