Answer:

30 waiters

Step-by-step explanation:

the ratio of 5 waiters to 2 cooks

you are given the total number of waiters and cooks = 42

write equation

x (5 + 2) = 42

7x = 42

x = 6

now distribute the x into waiters which is 5x or 5(6) = 30 waiters

additionally 2x is for cooks or 2(6) = 12 cooks; which adds up to 42
