Answer:
Explanation:
To determine how many necklaces Henry needs to sell for his revenue to equal his expenses, we can use the following steps:
1. Calculate the total expenses:
- Each necklace has an expense of $2.50.
- The total expense for a single necklace, including supplies, is $2.50 + $120 = $122.50.
2. Calculate the revenue from selling one necklace:
- Henry sells each necklace for $10.
3. Find the number of necklaces needed to cover the expenses:
- Divide the total expenses ($122.50) by the revenue per necklace ($10):
$122.50 / $10 = 12.25.
Since we can't sell a fraction of a necklace, Henry needs to sell at least 13 necklaces (rounding up from 12.25) to cover his expenses.
Therefore, Henry needs to sell at least 13 necklaces for his revenue to equal his expenses.
