POSSIBLE POINTS: 10 Betty Crocker has 25 pounds of chocolato. She uses 15 pounds to bake some cakes. What percentage of chocolate does she have left?

Answer 1

Given:

10 Betty Crocker has 25 pounds of chocolate.

So, x Betty Crocker has 15 pounds of chocolate

Using the ratio and proportion to find x

So,

$\frac{x}{10}=\frac{15}{25}$

Solve for x

$x=10\cdot\frac{15}{25}=6$

So, she uses 6 Betty Crocker

The remaining = 10 - 6 = 4

So, the percentage will be =

$\frac{4}{10}\cdot100=40\%$

So, the answer will be:

The percentage of chocolate does she have left = 40%
