Answer:
$30 per Ticket
Step-by-step explanation:
There are 3 friends coming along you so that means you have to divide one number by 3. You have a $20 coupon so that meant you had to subtract 20 from 120. <em><u>20-120=100.</u></em>
Now, you have to divide 100 by the 3 friends then add 5 to each number.
<em><u>3 divided by 100=25+5=30</u></em>
<u>So, $30 is your answer</u>

Step-by-step explanation:
I'm sure you know how to find the slope of a line if you know 2 points
on it ... The slope is ...
(difference in y-values) / (difference in x-values) .
Right ?
OK. Each line in these tables is a point on the graph of the table.
Pick two points from the table, and you can get the slope of the line
from them.
The first table (Plan-A) has these points in it:
1 . . . . . $20.15
2 . . . . . $20.30
3 . . . . . $20.45
4 . . . . . $20.60
You want to find the equation of the line with these 4 points on it.
That means you need to find the slope and the intercept of the line.
Take any two points straight from the table. I'll use the first two:
1 . . . . . $20.15
2 . . . . . $20.30
There you have two points on the line: (1, 20.15) and (2, 20.30) .
The slope is (difference in 'y') / (difference in 'x').
Difference in 'y' = (20.30 - 20.15) = 0.15
Difference in 'x' = (2 - 1) = 1
Slope of the line = (0.15) / 1 = <u>0.15</u>
(What that really means is 15 cents per minute on Plan-A.)
Now you know that the equation of the line is [ <u>y = 0.15x + intercept</u> ].
Can you think of a way to find the intercept ?
Remember ... every point in the table is on the line.
So why not just take one of these points in the table, put it into the part of the equation that you already have, and watch the intercept fall out ?
You could use any point at all from the table.
I'll use the 3rd one.
<u>y = 0.15x + intercept</u>
20.45 = 0.15(3) + intercept
20.45 = 0.45 + intercept
Subtract 0.45 from each side: <u>20.00 = intercept</u>
The equation of the graph for Plan-A is <em>Charge = 0.15(minutes) + $20.00</em>
===============================
Plan-B:
First two points:
Difference in y-values = (8.00 - 6.50) = 1.50
Difference in x-values = (10 - 5) = 5
Slope of the line = (1.50) / (5) = .30 (30 cents per minute)
Intercept = 5.00
Charge = 0.3(minutes) + $5.00
======================================
Plan-C:
Slope = 4.50 / 10 = 0.45
Intercept = zero
=================================
Plan-D:
Slope = (16.50 - 11.00) / (30 - 20) = 5.5/10 = 0.55
Intercept = zero
In each plan, the intercept is the cost just to sign up, before you use
the phone, and then the slope is the cost for each minute of talking on it.
Answer:
Step-by-step explanation:
We have been given that a hockey goalie loses 2 3/5 rating points each time his team loses. His team loses 8 games in a row.
To find the number that will represent the change in goalie's ratings after losing 8 games we will multiply 8 by 
.
Let us convert our mixed fraction into improper fraction.
Therefore, will represent the change in the goalie's rating points.
