Answer
There are 3 Mr. Goodbars and 2 Mounds bars
Work Step by Step
g = # of Mr. Goodbars
m = # of Mounds bars
Total amount : g + m = 5
Fat equation
16.3g + 14. 1m = 70 + 7.1
16.3g + 14. 1m = 77.1
g + m = 5 can be written as m = 5 - g. Plug this into 16.3g + 14. 1m = 77.1
16.3g + 14. 1(5 - g) = 77.1
16.3 g + 70.5 - 14.1g = 77.1
2.2g = 6.6
g = 3
There are 3 Mr. Goodbars
Plug 3 into g + m = 5
g + m = 5
5 - 3 = m
2 = m
There are 2 Mounds bars
