Answer:
222
Step-by-step explanation:
Let L = number of boxes Linda sold.
Let P = number of boxes Penny sold.
The sold a total of 492 boxes.
L + P = 492
Penny sold 48 more boxes than Linda.
P = L + 48
Substitute P with L + 48 in the first equation and solve for L.
L + L + 48 = 492
2L + 48 = 492
2L = 444
L = 222
Answer: Linda sold 222 boxes.
Check:
Penny sold 48 more boxes, so she sold 222 + 48 = 270.
Add the numbers they sold: 222 + 270 = 492
The difference is 48, and the total is 492. Our answer is correct.
