Assuming you want an explanation and now numbers VVV
Step-by-step explanation:
The first column says those are the measurements for four people, since two is half of four you can divide all those measurements in half to fill out the "2 people" collum. To fill out the rest of the columns justs take the amount you just multiply. For example you'd need 1 tbsp of butter for two people, to find how much you need for six you multiply that by 3.
If you have any questions please ask, i hope this helps!
you would so 100 minus 25 (25 is just one charge fee) which is 75 then divide 75 into 15 which is the hourly pay, and get 5 which is the hours he must work
