Final answer:
To calculate Sarah's earnings from the bake sale, we need the selling price of chocolate chip cookies and brownies. Assuming a price, we multiply the quantity of each item by their respective prices and sum the results for total earnings.
Step-by-step explanation:
To determine how much money Sarah will earn from the bake sale, we would need to know the selling price of chocolate chip cookies and brownies. Since the cost has not been provided in the question or in the reference information, it's impossible to give an exact answer. However, if we assume the cost of each chocolate chip cookie and each brownie, we could calculate the total earnings by multiplying the number of each item sold by their respective prices.
For example, if Sarah sells each chocolate chip cookie for $1 and each brownie for $1.50, the calculation would be:
- 10 chocolate chip cookies × $1 = $10
- 8 brownies × $1.50 = $12
Add the two amounts together for the total:
$10 + $12 = $22 total earnings from the bake sale.
