per hot dog

1.19

per bag o' chips

Explanation:

5x +3y = 14.82

7 x+6y = 22.89

− 10x−6y = −29.64

7 x+6y = 22.89

−3x = −6.75

x=2.25

5⋅2.25+3y = 14.82

3y = 14.82 − 11.25

y = 3.57 /3 = 1.19

(2,1) and (3,6)

Slope = (6-1)/(3-2) = 5

y = mx + c
y = 5x + c

at point (2,1)
1 = 5(2) + c
1 = 10 + c
c = -9

y = 5x - 9
