Schach [20]

At some point, she will sell enough cards so that her sales cover her expenditures. So, the correct answer is ($40)

<h3> How did we figure this out?</h3>

Lola is making greeting cards, which she will sell by the box at an arts fair. She paid $50 for a booth at the fair, and the materials for each box of cards cost $8. She will sell the cards for $10 per box of cards.

We are going to use 50, 8 and 10 to find are answer.

Therefore, we are going to divide the numbers:

\boxed{50/10}

  • Division problem
  • 50/10
  • 8 x ? = 40
<h3 /><h3>What is the missing number?</h3>

First, we need to figure out 50/10:

\boxed{50/10=5}

\boxed{8x5=40}

5=40\\(50/10=5=8x5=40)

Therefore, at some point, she will sell enough cards so that her sales cover her expenditures. So, the correct answer is ($40)
