Total tips = x
Busboy gets 1 - 2/3 - 1/4 = 1/12 of x
1 waiter gets (2/3)/4 = 2/12 of x

(2/12)*x + (1/12)*x = 30
x = 120

Option D

We can let n = the total amount of tips and thus (2n/3)/4 = 2n/12 = n/6 is the amount that one waiter receives.

Since the waiters and managers receive 2/3 + 1/4 = 8/12 + 3/12 = 11/12 of the total tips, the busboy receives 1/12 of the total tips. Now we can create the equation:

n/12 + n/6 = 30

Multiplying the equation by 12, we have:

n + 2n = 360

3n = 360

n = 120

Answer: D
