You found a very cool new job selling tickets to ride a giant slide that has been set up at the beach. the giant slide owner says she will pay you commission in one of two ways. every weekend, you will get either $40 plus $5 for every giant slide ticket you sell or $70 plus $2 for every giant slide ticket you sell. a) what is the break-even point for these two commission plans the giant slide owner has created for you?

yes

step-by-step explanation:

yes

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.
