Answer 1

Answer: $7.10



(2,2.18) (3,3) (4,3.82) (5,4.64)

First find the rate of change using y1-y2/x1-x2


3-2.18/ 3-2

=0.82

Next, find the y-intercept or the flat rate

Use the formula y-y1=m(x-x1)

y-3=0.82(x-3)

y-3=0.82x-2.46

y=0.82x+0.54


Next, replace x with 8 for 8 tacos

y=0.82(8)+0.54

y=7.1
