This problem tells us that a computer shop charges $20 per hour or a fraction of an hour for the first two hours and an additional 10 per hour for each succeeding hour.
00:10
Find out how much you would pay to use one of their computers for three scenarios, 40 minutes, three hours, and 150 minutes.
00:17
So for our first scenario, 40 minutes is less than one hour, but it says that we pay $20 or $20 for the first two hours or a fraction of an hour.
00:28
So since this is between zero and one hour, that means that we're going to pay the $20 charge that we get, uh, 20 amount that we get charged for one hour.
00:39
So it'll cost 20 for 40 minutes.
00:42
For three hours, we can see that we have a total of three, which means for our first two we get 20 per hour.
00:48
So 20 times two for the first two hours we have.
00:51
But then it's an additional 10 per hour for each additional hour after the first two.
00:55
So the one additional hour we have on top of.
00:58
Of the two original, we'll get multiplied by 10.
01:01
So we'll have 20 times 2, which is 40, 10 times 1, which is 10...
