Answer:
y = 9/2x -6.5
Step-by-step explanation:
m = (7-(-2))/(3-1)
m = 9/2
b = -6.5
y = 9/2x -6.5

You can work these in your head if you consider the revenue generated by the least contributor (children's tickets) and the difference in revenue between that and the larger contributor ($2.00 -1.50 = 0.50).
If all were children's tickets, the revenue would be 500*$1.50 = $750.00. The actual revenue exceeded that amount by $862.50 -750.00 = 112.50. This difference in revenue is made up by the sale of $112.50/$0.50 = 225 adult tickets. Then the number of children's tickets is 500 -225 = 275.
225 adult tickets were sold
275 children's tickets were sold.
_____
If you need an equation, you can write an equation using a variable for the number of adult tickets sold (the largest contributor).
.. (500 -a)*1.50 +a*2.00 = 862.50
.. 0.50a = (862.50 -750.00) . . . . . does this look familiar, yet?
.. a = 112.50/0.50 = 225
Answer:
The first four terms of the series are
= 14.25
Step-by-step explanation:
We know that
Sum of convergent series is also a convergent series.
We know that,
If the common ratio of a sequence |r| <1 then it is a convergent series.
The sum of the series is 
Given series,
The first four terms of the series are
Let
and 
Now for 
,
It is a geometric series.
The common ratio of is 
The sum of the series
=10.5
Now for 
It is a geometric series.
The common ratio of is 
The sum of the series
=3.75
The sum of the series is
= 
=10.5+3.75
=14.25
