This answer gives the correct total number of items sold, but not the correct total revenue. Nineteen apple pies sell for $\displaystyle{16}\cdot{12}={192}\usepackage{cmbright}\Huge\$ dollars, while 25 blueberry pies sell for $\displaystyle{25}\cdot{14}={350}\usepackage{cmbright}\Huge\$ dollars. This would be a total of $542, not $536. The correct equations with which to start the problem are:

(A) $\displaystyle{a}+{b}={41}\usepackage{cmbright}\Huge\$

(B) $\displaystyle{12}{a}+{14}{b}={536}\usepackage{cmbright}\Huge\$
