A student stuffs envelopes for extra income during her spare time. Her initial cost to obtain the necessary information for the job was $520. Each envelope costs S0.05 and she gets paid S0.09 per envelope stuffed. Let x represent the number of envelopes stuffed.
(a) Express the costC as a function of x.

erevenue R as a function of x.

b)

(c) Determine the value of x for which revenue equals cost
(d) Graph the equationsy=C(X) andy= R{x) on the same axes, and interpret the graph.

(a) C(x)=Cin dollars)
(Use integers or decimals tor any numbers in the expression)

after simplifying it i got: -36.25 as my answer. hope that !

the anwser is d) 75°

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.

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
