If three burgers and two fries cost 17.50, and two burgers and three fries cost 15.00, how much does a burger cost?

4.50

Step-by-step explanation:

If you use x for burgers and y for fries:

1) 3x+2y=17.50

2) 2x+3y=15

You can then do a simultaneous equation by multiplying the first equation by 1.5 to cancel out the y (fries) to get x (burgers) on its own

1) 4.5x+3y=26.25

2) 2x+3y=15

By subtracting the two equations you get 2.5x=11.25

Then divide 11.25 by 2.5, you get x =4.5 so a burger is 4.50

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
