This is one of those problems where you'll sink like a rock if you allow yourself to be blinded by all the useless, unnecessary, irrelevant information in the first paragraph.
The ONLY information you need is:
-- You're chartering a bus for 1 day. -- It costs $780 .
That's ALL .
(You don't even need to know that the bus has 55 seats. You might need that for #8 - #12, but not for #6 or #7.) _________________________
If the people on the trip are going to share the cost of the bus, then the cost of each share depends on the number of people.
Less people ==> each one pays more. More people ==> each one pays less.
Just like everybody in the office sharing the cost of a birthday gift for the boss.
#6 and #7 should really be done in the reverse order ... do #7 before you worry about #6. Before you can fill in the table in #6, you absolutely need to have the equation, whether or not you realize it.
The total cost is fixed . . . It's $780 .
If 2 people go on the trip, each one pays 780 / 2 . If 3 people go on the trip, each one pays 780 / 3 . If 4 people go on the trip, each one pays 780 / 4 . If 5 people go on the trip, each one pays 780 / 5 . . . If 10 people go on the trip, each one pays 780 / 10 . . . If 20 people go on the trip, each one pays 780 / 20 . . . If ' n ' people go on the trip, each one pays 780 / n . . . until the bus is full ... . If 55 people go on the trip, each one pays 780 / 55 . . If 56 people go on the trip, then you need another bus, and it gets more complicated.
But up to 55, the price per person is (780 / the number of people).
<span> #7). P = 780 / n .
</span>Now, filling in the table in #6 is a piece 'o cake.<span>
