Thank you. Just for clarification, is there a reason why it's 2 and not the others? Does it have something to do with the decimals?
Thanks!
Would this be right for d?
8 + (n - 1)0.75
= 8 + 0.75n - 0.75
= 0.75n + 7.25
Is there a reason for e) I would substitute n = 16 for a 15km trip and not n = 15?
I believe I did everything right
+67
