This recipe makes 20 cupcakes. Deepak only wants to make 15 cupcakes. How much of each ingredient does he need? Recipe: Makes 20

VashaNatasha [74]

Answer:

9.6 ounces of butter, 8 ounces of sugar, 12 ounces of flour, 4 eggs

Explanation: 20 / 16 = 4/5. 16 is four-fifths of 20. So multiply 4/5 with everything.

12 * 4/5 = 9.6 ounces

10 * 4/5 = 8 ounces

15 * 4/5 = 12 ounces

5 * 4/5 = 4 eggs

Rose bought a new hat when she was in vacation. If the hat cost $975 and the sales tax was 6%, how much did rose pay for the hat

Rufina [12.5K]

Hi!

To solve this, set up a proportion and cross multiply.

$\frac{x}{975} \frac{6}{100}$

975 x 6 = 5850

5850/100 = 58.5

58.5 + 975 = 1033.5

The answer is $1033.5

Hope this helps! :)
