Answer:
M=4.5+2.5d
Where m is the money and d is the additional day
Explanation:
The 4.5 is always going to be there since that’s the starting rent. The 2.5 is how much is charged every additional day,
EXAMPLE
If we test it out and say there are two additional days we have.
4.50$ for the first day charge
2.50*2 =5for the extra two days
So
4.50+5=9.5
