Question

Michelle bought 76 pounds of cocoa powder for her bakery. Every day she used the same amount of cocoa powder to make bakery items. After 10 days, Michelle was left with 20.2 pounds of cocoa powder. On average, how many pounds of cocoa powder did Michelle use each day? 5.58 pounds 7.45 pounds 9.62 pounds 12.6 pounds

Answer 1

76 - 10x = 20.2...where x is the total amount of cocoa used
-10x = 20.2 - 76
-10x = -55.8
x = -55.8 / -10
x = 5.58 lbs of cocoa <==

Answer 2

the answer is 5.58 because you do 76-20.2=55.8 then you divide it by the number if days passed so if it is 10 days then 55.8/10=5.58
