Find the rate of change and the initial value for the group lessons

Explanation / Answer

conconsider the points from table(1,17),(2,29)

slope=(y2-y1)/(x2-x1)=(29-17)/(2-1)=12

y=mx+b

now consider point(3,41)

41=12*3+b

b=41-36=5

y=12x+5

where y =total cost

x=hourly rate

cost to park for a day=24hours

total cost=12*24+5=$293

b)

if she rents for 3.5 hrs

total cost=12*3.5+5=$47

if she shares with her friend=$47/2=$23.5

lina has to pay 23.5
