The fixed income of Rick per week is the total of hours he works multiplied by the number of hours he actually works. Then the fixed income is


(11)(40)=440

To add the income he perceives per week in tips we have to multiply the average percentage per table by the cost of the table. Let x be the receipt of the tables. Then his income in tips is :


.18x

Therefore the groos income of Rick is:


y=440+.18x
