A rental car company charges drivers a flat fee to rent a car plus $0.25 for each mile they drive. If a drive pays $100 and drives 160 miles, which
equation can he use to find the his total cost y in terms of the number of
miles driven x?
*
A. y - 25 = (x - 40)
B. y - 40 = (x - 25)
C. y - 100 = 0.25(x - 160)
D. y - 160 = 0.25(x - 100)

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
