You buy 2 sodas and 4 candy bars for $6.50. The next day you buy
3 soda and 5 candy bars for $8.75. How much is each candy bar?
***
let x=cost of each soda
let y=cost of each candy bar
..
2x+4y=6.50
3x+5y=8.75
..
6x+12y=19.50
6x+10y=17.50
subtract
2y=2
y=1
2x=6.50-4y=2.50
x=1.25
cost of each soda=$1.25
cost of each candy bar=$1.00
