The algebraic expression is 20b
<h3>How to determine the algebraic expression?</h3>
The statement is given as:
$20 a ticket
This means that the cost of 1 ticket is $20.
So, the cost of b tickets is
Cost = 20 * b

Answer:
y = 2 ± 
Step-by-step explanation:
Solve using separable equations
First put x and dx on the same side and do the same for y
(y-2)dy = (x-2)dx
Now you can integrate
+ C1
Now we depending on how what ur instructor wants you may need to give exact solutions. We can do this by solving he quadratic equation for Y
Doing this you get:
y = 2 ± 
<em>Note C's were simplified.</em>
