10 chefs can prepare a meal for 536 people in 8 hours. Assuming that the chefs cook at the
same rate and that the rate at which they cook
remains constant throughout the preparation,
find the number of people 22 cheis can prepare
a meal for in 5 hours.

737 people I’m pretty sure

536 divided by 8 = 67 meals per hour
Divide that by the number of chefs (10) = 6.7 meals per chef every hour.

Then take the 6.7 and basically reverse the math with the new number of chefs and new number of hours:

6.7 x 22 chefs = 147.4 = meals per hour
147.4 x 5 hours = 737 meals made by 22 chefs in 5 hours.

Subtracting is the opposite of adding
