Question

The girls in Lana’s troop set a goal to sell 1,000 boxes of cookies this year. There are 13 girls in the troop. At least how many boxes of cookies should each girl sell to reach their goal?

Answer 1

Each girl should sell at least 77 boxes.

Explanation:

Considering the number of boxes and how many girls will them, just take
`(100)/(13) \approx 77`

The exact result is
`(100)/(13) = 76.923...`, but
`76 \cdot 13 = 988` and
`77 \cdot 13 = 1001`, therefore, 76 cannot be the result. So, each girl should sell at least 77 boxes.
