# 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. ##### 1 Answer Dec 5, 2017 Number of Prints = $15.4 \approx \textcolor{red}{15}$#### Explanation: Given: The equation; $- G = \left(G - 25 N\right) + 355$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;

$- 15 = \left(15 - 25 N\right) + 355$
$- 15 - 15 = - 25 N + 355$
$25 N = 30 + 355$
$N = \frac{\cancel{385}}{\cancel{25}} = 15.4 \approx \textcolor{red}{15}$

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