Answer:
- Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.
Explanation:
We know that:
- 48 + 8(b) = Carly's expenditure
- 10(b) = Carly's expenditure
- 48 + 8b = 10b
- B = Boxes of cards
Work:
- 48 + 8b = 10b
- => 48 + 8b - 8b = 10b - 8b
- => 48 = 2b
- => b = 24
Now, let's substitute the value of b into any equation.
Hence, Carly's expenditure was $240 and the number of boxes of cards was required is 24 boxes.
