Question

Joe's Bakery is making 120​ cupcakes for a large catering order. Their recipe calls for 5​ ounces of flour for 12​ cupcakes. How much flour will they need for their catering order? Enter a whole number of pounds (lb) and enter the ounces (oz) as a number between 0​ and 15​, using the fact that 1​ lb = 16​ oz.

Answer 1

Joe's Bakery will need 3 pounds and 2 ounces of flour for the catering order. This is calculated by using the ratio from the original recipe and scaling up to the quantity needed for 120 cupcakes.

Step-by-step explanation:

To find out how many ounces of flour Joe's Bakery needs for 120 cupcakes, we need to set up a proportion based on the given information. Since the recipe calls for 5 ounces of flour for 12 cupcakes, we can calculate the amount of flour needed for 120 cupcakes by scaling up the quantity.

First, we find how many times the original 12 cupcakes fit into the 120 cupcakes needed for the order:

120 cupcakes ÷ 12 cupcakes = 10

Then, we multiply the amount of flour needed for 12 cupcakes by this factor:

5 oz of flour x 10 = 50 oz of flour

Next, we convert ounces to pounds, remembering that 1 pound is equivalent to 16 ounces:

50 oz ÷ 16 oz/lb = 3 lb with 2 oz leftover

Therefore, Joe's Bakery will need 3 pounds and 2 ounces of flour for the catering order.
