Brand A costs $2 per ounce, B is $1, C is $0.50(?) I think
Plug in g equals -5 x -2 which equals 10 because 2 negatives are a positive then 10-6 equals 4
The anwser is 4
What you want to do is cross multiply so you get 5(x+4)=7(3x+28) then you distrubute the 5 and then you distribute the 5 and the 7 to the number in the parentheses 5x+20=21x+196
subtract 5x on both sides to get 20=16x+196 then you subtract 196 on both sides to get -176=16x last what you want to do is divide 16 on both sides to get x=-11

The city named Portland can be found in both states.
