Answer 1

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`
