Total burgers by 3 chefs:
3 chefs........225 burgers.....5 hours

Total burgers by 3 chefs per hours  
3 chefs........45 burgers.......1 hour

Total burgers by 1 chef per hour  
1 chef.......15 burgers..........1 hour

Now, 750 burgers were made in 10 hours on the weekend, which means 75/10 = 75 burgers were made per hour.

Let x be the total number of chefs working on the weekend.

Thus, 15x = 75
x = 5

3 were already working with the restaurant. So the restaurant employed 2 more on the weekend.

Answer is D.
