Incorrect. Let $\displaystyle{t}=\usepackage{cmbright}\Huge\$ Julie's time, in minutes, to eat a tableful of pies. Then $\displaystyle{1.5}{t}=\usepackage{cmbright}\Huge\$ Shawna's time to eat a tableful. So their rates are $\displaystyle\frac{{1}}{{t}}\usepackage{cmbright}\Huge\$ and $\displaystyle\frac{{1}}{{{1.5}{t}}}\usepackage{cmbright}\Huge\$ tablefuls per minute. Use this fact to find their combined rate. Then set up an equation using the fact that rate times time equals amount of work done. Solve for t, then find $\displaystyle{1.5}{t}\usepackage{cmbright}\Huge\$ .
