Answer:
5.15
Step-by-step explanation:
A rational number is any number that can be expressed as the quotient or fraction of two integers, a numerator and a non-zero denominator
Given, a parking lot charges $3 for first hour and $2 per hour after that.
So for t hours, the parking lot charges $3 for the first hour and after first hour there is
hours left.
So for
hours it will charge $2 per hour.
The charges for
hours = $
.
Total charges for t hours for one car = $
Now for the second car, it will charge 75% of the first car.
So the charges for second car
=$[
]
=$
There are 3 cars. That parking charges for the third car is also 75% of the first car.
So for third car the parking charges are same as for the second car.
Total parking charges for 3 cars
= $
= $
We have got the required answer here.
The correct option is option C.
-3x from both sides so it looks like 2x=20 and divide by 2 and x=10
Would it be 4(1)^2+2(2(1)+2)^2=100
