Answer:
$34,000
Step-by-step explanation:
We can find the costs for each college by multiplying the yearly cost by 4:
First, find the cost for the public university:
6500(4)
= 26000
Then, find the cost for the private college:
15000(4)
= 60000
Next, find the difference between the two costs:
60000 - 26000
= 34000
So, it will cost him $34,000 more to attend the private college
This is a number you will have memorized in grade school. If not, you can always perform long division of 2 by 3 to find it---or ask your calculator.
2/3 = 0.6666_6 . . . . . . repeating 6s indefinitely
____
Most folks get tired of writing 6s after a couple million of them, so they round it off to 0.67 or 0.667. These rounded values are NOT exactly 2/3.
Answer: 153
Step-by-step explanation:
When we have a group of N elements, the total number of combinations of K elements ( K ≤ N) is:

Where N! = N*(N - 1)*(N - 2)*...*2*1
In this case, we have a group of 18 people (then N = 18) and we want to see how many different combinations of 2 we can make (K = 2).
Using the above equation we get:

There are 153 different ways in which the manager can do this.
