1 Ounce of Butter = B
Bowl of Curry = C
1 Hour = H
----------------
A restaurant requires 4 + 1/2 ounces of butter for every bowl of curry it makes...
C = 9/2 B
In an hour, an average of 2 + 1/2 bowls of curry is served...
H = 5/2 C
... Which means that: H = 5/2 9/2 B
... So: H = 45/4 B
The question was: How many ounces of butter are required in 1 + 1/2 hours?
Here is the answer:
3/2 H = 3/2 45/4 B
3/2 H = 135/8 B
In words, 16 + 7/8 ounces of butter would be required over a period of 1 + 1/2 hours.
