Given the information that initial tuition cost is $100 and it's increasing by 6%.
00:05
We'd like to know what the new cost of tuition will be.
00:09
Then what we're going to suppose is that it's decreasing by 6 % from that new value.
00:13
We'd like to know if the new tuition will be back to that $100, given that we saw that 6 % increase and now we're seeing a 6 % decrease.
00:20
So let's start with this first part.
00:22
So we have this initial tuition which is equal to $100.
00:25
We're told it's increasing by 6%.
00:28
So to calculate that, what we need to do is take this 1%.
00:30
$100, multiply that by 1 .06.
00:36
And the way that i got this 1 .06 is we know that it's increasing by that 6%.
00:41
And 6 % can be written in decimal form as 0 .06.
00:47
So because it's that increase, we know we're still going to have that 100 % of the $100.
00:54
But in addition to that, we have the 6%.
00:57
So we have 1 .06.
00:59
And you can see that.
01:00
Again, 100 % would just be written as 1.
01:04
So we can just add these two values together to give us 1 .06...
