<h3>
Answer: 39</h3>
========================================================
Explanation:
You can use the nCr formula shown below

where n = 39 and r = 1. However, you could also use the identity

which basically says there are n ways to pick 1 item if you are given a choice of n items. In this specific case, we have 39 items total, and there are 39 ways to pick one item.
First of all, you did not tell me much, how much is it for 1 hour of service?
First things first, you will have 94 + x. Place those on top of a fraction bar and on the bottom put the two numbers over 2. So you have 94 + x over 2. Then, write the symbol ‘greater than or equal to’ and on the other side place your 90. So, 90 + x over 2 is greater than or equal to 90. This is a difficult thing to write out and explain so I hope this makes sense. :)
