Question 1153472
<br>
A formal algebraic solution will be somewhat complicated....<br>
So solve the problem with trial and error, a little mental arithmetic, and logical reasoning.<br>
Obviously the number of people has to be a whole number; and it needs to be a number that is reasonable, assuming the "taxi" is not a bus.<br>
5 people paying $40 means $8 each; 4 people paying $40 means $10 each.  That difference is EXACTLY $2; logical reasoning then tells us that if the difference is LESS THAN $2, the original number of people has to be MORE THAN 5.<br>
ANSWER: The number of people has to be greater than 5.<br>
