10-120.

Betty’s Quick Stop makes a $15\%$ profit on its lunches and a $22\%$ profit on its dinners. If Betty took in $\2700$ on Tuesday and made $\513.01$ profit, how much did Betty take in on lunch? Write one or two equations, then solve.

One equation is: (lunch $\$) $+$ (dinner $\$) $=\2700$
Now write an equation for the profit and solve the system.
