For this case you can solve the problem by a simple rule of three:
72 ---> 100%
x ---> 30%
Clearing x we have:
x = (30/100) * (72) = 21.6 $
Then, we must subtract this value from the original price:
72-21.6 = 50.4 $
answer:

Answer:
7 1/2 cups
Step-by-step explanation:
1 1/2 cups x cups
---------------- = ------------------
7 pancakes 35 pancakes
using cross products
1 1/2 * 35 = 7 * x
change 1 1/2 to an improper fraction (2*1+1)/2 = 3/2
3/2 * 35 = 7x
105/2 = 7x
divide each side by 7
105/2 * 1/7 = x
15/2 =x
change back to a mixed number
2 goes in to 15 7 times with 1 left over
7 1/2 cups
