10-128.

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

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