From the question stem, we can deduce the following information
\(x + 10*\frac{3x}{5} + (n-10)*\frac{x}{5} = 45\) where n = total number of prints.

Substituting the value for n = 20,\(x + 6x + 2x = 45\) -> \(x = \frac{45}{9} = 5\)

Therefore, the total charge of making a negative and 20 prints is 5(Option E)

We can create the equation:

45 = x + 10(3x/5) + 10(x/5)

45 = x + 6x + 2x

45 = 9x

5 = x
