Answer 1

First we must define variables:
 x: number of Snickers candy bars
 y: number of KitKat bars
 We write the system of equations:
 27.50x + 21.50y = 119.50
 48x + 36y = 204
 Solving the system we have:
 x = 2 packages
 y = 3 packages
 Answer:
 she did buy:
 2 packages of Snickers candy bars
 3 packages of KitKat bars
