how much fat does one scoop of ice cream have

Question

sarah and monique make an ice cream sundae. sarah gets 2 scoops of cherry ice cream and 1 scoop of mint chocolate chunk ice-cream for a total of 60 g of fat. tara has 1 scoop of cherry and 2 scoops of mint chocolate chunk for a total of 57 g of fat. How many grams of fat does 1 scoop of each type of ice cream have?

Answer 1

2c + m = 60

c + 2m = 57

 

m = 60 - 2c

 

c + 2(60 - 2c) = 57

c + 120 - 4c = 57

-3c = -63

c = 21 g

 

m = 60 - 2(21)

m = 60 - 42

m = 18 g
