Answer:
x + y = 220
25 x + 15 y = 4650
The above system can be used to find the number of adult and student tickets sold.
Step-by-step explanation:
Let us assume the number of Adult's ticket sold = x
And The number of student's tickets sold = y
Now, total number of tickets sold = 220
⇒ x + y = 220
Cost of 1 adult Ticket = $ 25
⇒ Cost of x adult tickets = x ( $25) = 25 x
Cost of 1 student Ticket = $ 15
⇒ Cost of y student tickets = y ( $15) = 15 x
Also, the total amount made from selling all tickets = $4650
⇒ 25 x + 15 y = $4650
Here, the given system of equations are:
x + y = 220
and 25 x + 15 y = 4650
The above system can be used to find the number of adult and student tickets sold.
The number is 6400.
We have given that,
divided 80 by my number, and then added 13.
<h3>What is the expression?</h3>
An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Suppose the number is x

Subtract 13 from both sides


Multiply both sides by 80

x=6400
Therefore the number is 6400.
