How to work out hours based on known percentages

[AmyTaylor]

Hi, i have a question which will probably be very easy for you guys, but i dont know the answer.
Please show your workings., I want to solve this using an excel worksheet...

I have a budget of 500,000 and 3 things to spend it on, A, B & C
And we assume that A will cost 9 per hour, B costs 14 and C 15 per hour.

How many hours each can we spend on each if we want
20% of the hours to be bought be A, 20% by C and 60% by C.

Many thanks.
Amy
