Raj is a dog walker. He charges $85 walking fee and $20 per dog, with the first dog free. Which equation could you use to calculate the cost, c, to have Raj walk d dogs?
A.=c=85+20(d−1) B. c=85(d−1) C.c=20+85(d−1) D.c=(85+20)(d−1)
clearly, A
The correct equation to calculate the cost, c, to have Raj walk d dogs is:
C. c = 20 + 85(d - 1)
To calculate the cost, c, to have Raj walk d dogs, we can break it down into two parts.
First, we know that Raj charges a walking fee of $85. This fee is constant regardless of the number of dogs being walked.
Second, Raj charges an additional $20 per dog, but the first dog is free. So, for each additional dog (d-1), Raj charges $20.
Therefore, the equation that represents the cost, c, to have Raj walk d dogs would be:
c = 85 + 20(d-1)
This equation takes into account the walking fee of $85 and the additional $20 per dog, excluding the first dog.
Therefore, the correct answer is A. c = 85 + 20(d-1).
