Final answer:
The 8th graders raise a total of $75.30 by selling 74 cupcakes at $0.45 each and 56 brownies at $0.75 each.
Step-by-step explanation:
Calculating Total Sales from a Bake Sale
To calculate the total money raised by selling cupcakes and brownies, we need to multiply the number of each item sold by its respective price and then sum the totals. According to the given bake sale prices, brownies cost $0.75 each and cupcakes are priced at $0.45 each. The 8th graders sell 74 cupcakes and 56 brownies.
The total raised from selling cupcakes is 74 cupcakes × $0.45 per cupcake = $33.30. The total raised from selling brownies is 56 brownies × $0.75 per brownie = $42.00. Therefore, the total money raised by the 8th graders is $33.30 + $42.00 = $75.30.
The correct answer is (b) $75.30.
