The cost of a cab ride is $10 for the first mile or part of a mile. It costs $3 for each additional mile or part of a mile and all cab rides are less than six miles. The cost is modeled by the function C(m), where "m" is the number of miles. The driver's pay "P" is a function of the cost "C" and is modeled by P(C) = 0.60C. What is the domain of P(C)?

Answer: {10, 13, 16, 19, 22, 25}

Explanation:

Cab ride cost for first mile = $10

Additional mile cost = $3

Therefore, the following cab cost for different miles are analysed:

Cab ride cost for first mile = $10

Cab ride cost for second mile = $10 + $3 = $13

Cab ride cost for third mile = $10 + $3 + $3 = $16

Cab ride cost for fourth mile = $10 + $3 + $3 + $3 = $19

Cab ride cost for fifth mile = $10 + $3 + $3 + $3 + $3 = $22

Cab ride cost for sixth mile = $10 + $3 + $3 + $3 + $3 + $3= $25

Therefore, th domain of P(C) will be equal to {10, 13, 16, 19, 22, 25}
