Question 125179: Hello!! Can someone try and solve this one, I not understanding this. Thank You so much!! --For the following function, C computes the cost in millions of dollars of implementing a city recycling project when x percent of the citizens participate. it is supossed to be shown like: "C(x)=1.5x over 100-x" (1.5x/100-x)
a) Using this model, approximately what is the cost if 60% of the citizens participate?
b) Using this model, estimate the percentage of participation that can be excepted if $5 million is spent on this recycling project? Set up an equation and solve algebraically. Round to the nearest whole percent.
You can put this solution on YOUR website! C(x)=(1.5x/100-x)
a) Using this model, approximately what is the cost if 60% of the citizens participate?
C(60) = (1.5*60/(100-60)) = 90/40 = 9/4 = 2.25 million dollars
----------------------
b) Using this model, estimate the percentage of participation that can be excepted if $5 million is spent on this recycling project? Set up an equation and solve algebraically. Round to the nearest whole percent.
5 = (1.5x/(100-5)
5 = (1.5x/(95-x))
475-5x = 1.5x
475 = 6.5x
x = 73.08%
