erastova [34]
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>

</span>5 people. . . . . . . 780 / 5
10 people . . . . . 780 / 10
15 people . . . . . 780 / 15
20 people . . . . . 780 / 20
.
.
etc.

Just don't go past 55 people.  The equation changes after that.

For ANY number of people, even hundreds, and ANY number
of buses, I think the equation looks something like this:

                P  =  (785/n) · [ 1 + int(n/56) ]  .

' int ' means ' the greatest integer in ... ', that is,
                     ' throw away the fractional part of the quotient,
                       and use only the whole number '.

rewona [7]

Answer:

Option 2: (1,0) is the correct answer

Step-by-step explanation:

Given inequality is:

y>-5x+3

In order to find which point is solution to the given inequality we'll put the point one by one in the inequality. If the point satisfies the inequality, then the point is the solution of the inequality.

Putting (0,3) in inequality

3 > -5(0)+3\\3>0+3\\3>3

Putting (1,0) in inequality

0>-5(1)+3\\0>-5+3\\0>-2

Putting (-3,1) in inequality

1 > -5(-3)+1\\1> 15+1\\1>16

Putting (-1,-2) in inequality

-2>-5(-1)+3\\-2>5+3\\-2>8

The inequality is true for (1,0)

Hence,

Option 2: (1,0) is the correct answer
