Lorico [155]

Answer:

The answer to your question is $1.29

Step-by-step explanation:

Data

Total amount of cupcakes = 50

Total amount of sugar = 3 1/2 cups = 3.5 cups

Cost of 5-pound bag = $3.69

2 cups = 1 pound

Total cost = ?

Process

1.- Calculate the amount of pounds needed

                  2 cups ------------------ 1 pound

                  3.5 cups ---------------  x

                  x = (3.5 x 1) / 2

                  x = 3.5 / 2

                  x = 1.75 pounds

2.- Calculate the price of 1.75 pounds

                  5 pounds -------------- $3.69

                  1.75 pounds ----------    x

                  x = (1.75 x 3.69)/5

                  x = 6.46/5

                 x = $1.29

3.- Conclusion

The cost of sugar to prepare 50 cupcakes is $1.29

Hi there!

The key in the question is "divide". Therefore, we divide 5 by 3

5/3=1.6 pounds

I don't think any of these are right.
