Answer:
77 boxes
Step-by-step explanation:
Step 1:
Lana's troop must sell 1000 boxes of cookies, but there are 13 girls in total. <u>Supposing that each girl will sell an equal amount of boxes</u>, we can simply <u>divide</u>:
÷
boxes.
Step 2:
However, <u>it would seem unlikely that the girls would decide to sell fractions of a box of cookies</u>. We should round...up or down?
If we round down, each girl will sell 76 boxes of cookies. Hmm... then they would'nt be able to sell a total of 1000 boxes of cookies! We need to round up.
<u>Therefore, each girl should sell at least </u>
<u> boxes.</u>
