There are 110 calories per 28.4 grams of a snack. How many calories are in 42.6 grams?
110/28.4= x/42.6
110(42.6)=4260
4260/28.4=x
x=150
 
- - - - - - - - - - - - - - - - - -
28.4 ---- > 110

42.6 ---- > x ??

=> 28.4*x = 110*42.6

=> x = 165 Calories.

110(42.6)=4260<<<< This should be 4686

x = 4686/28.4

x = 165


4260/28.4=x
x=150
