Question

How do you solve this ?

![A printer determines its earnings by the number of impressions made through the equation:]
G = Profitability
N=Number of prints
Determine the number of prints for a $15 profit.

Answer 1

Number of Prints = `15.4 approx color(red) 15`

Explanation:

Given:

The equation;
`-G = (G -25N) + 355`

Where,

G = Profitability
N = Number of Prints

For determining the Number of Prints for a $15 Profit, we substitute 15 for G in the equation, that is;

`-15 = (15 - 25N) +355`
`-15 -15 = -25N +355`
`25N = 30 +355`
`N = cancel(385)/cancel(25) =15.4 approx color(red)15`

Therefore, the Number of Prints for a $15 profit would be 15.
