Answer:
A. $6
Step-by-step explanation:
We are given the table representing the number of days and the total charges in dollars.
So, the rate of change of the amount is given by, 
The linear equation representing the situation is,
Total charges = Fee per days + Fixed amount.
i.e. Total charges, y = Rate multiplied by x + Fixed amount (c)
So, substituting the rate and the point (0,6), we get,
6 = 10 × 0 + c
i.e. c = 10
Thus, the equation is,
Total charges, y = Rate multiplied by x + Fixed amount (c)
i.e. y = 10x + 6
Hence, the fixed amount charged is $6.
So, option A is correct.
