per " bottle of water "= $3.00
per " pretzels" = 3.50
2x3.00=6
3x3.50= 10.50
you add them together you get 16.50
for the second part
4x3=12
1x3.50=3.50
you add them together you get 15.50
per " pretzels" = 3.50
2x3.00=6
3x3.50= 10.50

2w + 3p = 16.50
4w+p = 15.50
double the first:
4w+6p = 33
4w + p = 15.50
subtract them
5p = 17.50
p = 3.50
into the original 2nd:
4w + 3.50 = 15.50
4w = 12
w = 3.00
Water costs $3.00 per bottle, and $3.50 per pretzel
4w+p = 15.50
double the first:
4w+6p = 33
4w + p = 15.50

5p = 17.50
p = 3.50
into the original 2nd:
4w + 3.50 = 15.50
4w = 12
w = 3.00
Water costs $3.00 per bottle, and $3.50 per pretzel
