Let's use ratio and proportion or rates to solve thisIf there is 5/6 cup of cinnamon in a 3/4 pound of spice mix, how many are in a pound?5/6=3/4 ?=11/ (3/4)*5/6=11/9Therefore there are 10/9 cups of cinnamon in 1.111... or 11/9 pounds of spice mix.
In order to calculate the equivalent discount, consider the principle number is 100,
Then, 100 - 100 * 0.20 = 100 - 20 = 80
Now, 80 - 80 * 0.15 = 80 - 12 = 68
So, Total discount would be: 100 - 68 = 32%
Hope this helps!
