0.10c + 0.12b = 2.18
c = 4b + 1
0.10(4b + 1) + 0.12b = 2.18
0.40b + 0.10 + 0.12b = 2.18
0.40b + 0.12b = 2.18 - 0.10
0.52b = 2.08
b = 2.08 / 0.52
b = 4 <==== she had 4 bottles
c = 4b + 1
c = 4(4) + 1
c = 16 + 1
c = 17 <=== she had 17 cans

The absolute value of -27 is 27, so it is the same number
I believe 1/9=9, 2/9=18, 3/9=27, 4/9=36
Don't get mad if you get it wrong.
