I need to reverse a formula that was given to me in an equation.
The problem is..
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.
The formula is
C(x) = 1.5x
100 - x
I solved that...... now it says...
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.
I have no clue how to turn the equation around.
It's been 25 years since I took algebra in highschool and I'm expected to regurgitate it for College Algebra... can anyone atleast help me with setting up the formula?
Thanks in advance!!
