Answer:
$40
Step-by-step explanation:
200 - 20% = 160
200 - 160 = 40
He drives 55 miles per hour for x hours. You want to multiply the number of hours by his speed , so you have 55x.
Then you want to subtract that from the total miles he has to drive.
The equation is Y = 385 - 55x
The probability is 5/343.
Given :8 floors and 4 passengers.
Passengers will be assumed to start on the first floor, where everyone goes up, and each passenger only gets off on the 2nd floor (no one gets off on the 1st floor!)
Now we need to find the number of all ordered lists of four numbers out of seven, eg 2<3<7<8, 3<6<7<8, 4<5<6o<8, etc.
This can be done in 7C4 ways.
The total numbers of ways 4 passengers can get off at 7 floors (starting at the 2nd!) is .
Therefore the probability is =
