Nevermind, I figured it out.

10hrs (max possible) of tutoring at $15/hr = $150

10hrs of delivery at $8/hr = $80

for a total of $230.

I would set up a function to be maximized, and then read through the constraints and list them:

let y= pizza hours

let x = tutor hours

then we want max of 15x + 13y, where x+y <= 20 and x <= 10. (x , y > 0).

Graph the equations, find vertices, plug vertex coordinates in to 15x +13y, find max altered vertex value.

Should leave you with 230$ possible max profit.
