Question 113393: what am i doing wrong?
� = 3 � (2x-1)/(x+2)
� * 4(x+2) = 3 � {(2x-1)/(x+2)} *4(x+2)
x + 2 = 3 � (2x � 1)4
x + 2 = 3 � (8x � 4)
x + 2 = 7 � 8x
x + 2 � 2 = 7 � 2 � 8x
x +8x = 7 � 8x +8x
9x = 7
9x/9 = 7/9
x = 7/9

Question 113785: C computes the cost inmillions of dollars of implementing a city recycling project when x percent of the citizens participate. C(x)=1.4x/(100-x)
Using this model, approx what is the cost if 60% of the citiznes participate?
this is what I have - is this correct? C=1.4 times 60 over 100-60, which would be 2.1 million.
I do not know how to write the formula for part b, which is to estimate the percentage of participation that can be expected if 4 million is spent on the project. Set up an equation and solve algebraically, rounding to the nearest whoel percent.
