The cost, c(x), for a taxi ride is given by c(x) = 3x + 2.00, where x is the number of minutes. What does the slope mean for thi
s situation? A. The rate of change of the cost of the taxi ride is $3.00 per minute.
B. The rate of change of the cost of the taxi ride is $2.00 per minute.
C. The taxi ride costs a total of $3.00.
D. The taxi ride costs $2.00 per trip.
Pay attention to the y=mx+b form where m=slope-->>
3x is the slope...
so it's 3(times the number of minutes) <<---or (x)
This means that the slope is 3, or the fancy way of saying it-->>"rate of change." The rate of change of the cost of the taxi ride is $3.00 per minute. Thus, your answer.
If he's been at the gym for 6 months, and he is charged $20 each month, then he has paid $120 dollars, not counting his membership fee. His total bill is $150.
225 divided by 5 equals 45. You can now use this ratio to determine the number of people with different amounts of buses; when you change x from 1 to n, you would need to multiply 45 by n, and you will have your new ratio column in the table.
