Answer:
The fixed amount that is charged is:
$ 25
Explanation:
The table is given as follows:
Number of days(x) Total charge(in dollars)(y)
0 25
1 40
2 55
We know that the fixed amount is the amount of money that is charged irrespective of the days, i.e. it is the initial amount that is charged.
i.e. based on the table is the value of y when x=0
From the table we see that when x=0 , y=25
Also, the equation that determines the relation between x and y is:
y=15x+25
Hence, the fixed amount that is charged is:
$ 25
