Question 46398
3x + 1y =1.75
2x + 4y =2.00

To find the cost of the choclate bar we must eliminate the gum from our equation.

One way to do that is to Multiply the first equation by 4 and substract the two equations

4(3x+Y)= 1.75
 12x +4y = 7.00 now substract the 2nd equation from first
- 2x +4y = 2.00 you get the following equation

10x= 5.00 solve for x by dividing both sides by 10
x=.50

solve for y by plugging in value for x in either equation.

2*(.5) + 4*y = 2.00
1.00+4y=2.00
4y=1.00
y=.25
