We have two equations: 8i+4w = 964 4w+8c = 756 We can add the two equations, i.e., add the left-hand sides and add the right-hand sides: 8i+8w+8c = 964+756 = 1720 Now divide the equation by 8 and get i+w+c = 215 9/2/2013 | Andre W. Best answer Comment
I think you are asked how much do 1 mint, 1 curly wurly, and 1 carmac cost together. Otherwise there is not enough information to solve the problem. Well, let x be the cost of 1 mint, y--the cost of 1 curly wurly, and z--the cost of carmac. We have the following equations: 8x+4y=956 4y+8z=756 Add them together to obtain this: 8x+4y+4y+8z=1720 or 8x+8y+8z=1720 From the last one you can obtain 8(x+y+z)=1720 or x+y+z=215. 9/2/2013 | Kirill Z.
