ok well first you got to find out how much each bottle of Brand A is..
26 divided by 2 equals 13
just to make sure you do another one
65 divided by 5 is 13
ok so each bottle is $13
then you times
13 times 7 equals 91
For Brand B y=16x
So you take x which is our bottle and times it
16 times 7 equals 112
so Brand A is $91 and Brand B is $112
To find the difference you subtract
So 112 minus 91 equals 21
