X = 5 boxes
<u><em>figure out the X for each person</em></u>
<u>Lizzy sold</u>: 5 * 5 = 25 boxes
<u>Suzy sold</u>: 5 * 1 = 5 boxes
<u>John sold</u>: 5 * 3 = 15 boxes
<u>Mark sold</u>: 5 * 8 = 40 boxes
<u>Lamar sold</u>: 5 * 4 = 20 boxes
→ How many boxes did Lamar sell?
Answer: 20 boxes
→ How many more boxes did John sell than Suzy?
Answer: 10 boxes
<u><em>workout</em></u>: 15 boxes - 5 boxes = 10 boxes more
→ How many more boxes would Lizzy have to sell to equal how many Mark sold?
Answer: 15 boxes
<u><em>workout</em></u>: 40 boxes - 25 boxes = 15 boxes more
