Answer:
390
Step-by-step explanation:
We need to find the slope of the data
m = (y2-y1)/(x2-x1)
= (90-60)/(4-2)
=30/2
= 15
y = 15x +b
Let (10,180) =x,y
180 = 15*10 +b
180 = 150+b
Subtract 150 from each side
180-150 =150+b-150
30=b
The equation is y = 15x+30
We want to rent it for 24 hours
y = 15*24 +30
360+30
y = 390
