Question 1204350
<br>
The problem is clearly stated incorrectly.<br>
As the problem is given, $27 is the cost of the tour bus -- not the cost per person of the tour bus.<br>
But to get a whole number answer for the number of friends in the group, you have to use $27 as the cost per person for the tour bus.<br>
So the response from tutor @Math_Tutor2020 is the correct response for the problem as stated.<br>
