Answer:
One bag of chips costs $1.10
One can of soda costs $0.50
Step-by-step explanation:
1. Create a system of equations (b = bags of chips | s = soda)
10b + 8b = 15
5b + 5s = 8
2. Use the Elimination method by multiplying 5b+5s=8 by -2
10b + 8b = 15
-2(5b + 5s = 8)
=
10b + 8b = 15
- 10b - 10s = -16
(10b and -10b will cancel out, so you will only have s left)
=
-2s = -1
Divide by 2
Soda = 1/2, or $0.50
3. Plug in S (0.50) into an equation above and get B by itself
5b + 5(0.50) = 8
=
5b + 2.5 = 8
- 2.5 -2.5
5b = 5.5
Bag of Chips = $1.10
