Answer:
The piece-wise function is;

Step-by-step explanation:
The flat rate for renting the car = $35 per day
The amount charged as insurance fee per day for renting the car for 3 days or less = $10
The insurance fee charged per day when the car is rented for more than 3 days = $5
Let the number of days = x
Therefore, we have;
For x ≤ 3, f(x) = 35 × x + 10 × x = x × (35+10) = 45·x
For x > 3, f(x) = 35 × x + 5 × x = x × (35+5) = 40·x
Therefore;
The charge rate for renting the car for less than or equal to 3 days = 45·x
The charge rate for renting the car for more than 3 days = 40·x
The piece-wise function can be presented as follows;

It is given that price of 3 muffins = $3.25
So price of 1 muffin=

And cost of 12 muffins

Therefore cost per dozen of muffins is $13 .

Step-by-step explanation:
the question is asking for the volume of water in m^3 that will be in the pool when it is completely full.
we find this by multiplying the length times the width times the depth.
this gives us 50m×25m×2.5m= 3125m^3
Answer:
a square would be 2 times of the sides. And what rug?
Step-by-step explanation:
Answer:
Take 1651 divided into 13 you get 127 so they can buy 127 posters . Then they sold them for 20 dollars a piece so take 20 times 127 which is 2,540 dollars that’s the money they got .
