Let x be her weekly allowance.
Susan spent $8 of her allowance going to the movies, so x-8=20. Also she gave the dog a bath and earned $5, so our equation now is x-8+5=20.
Now we can solve for x to get the value of her allowance:
[tex]x-8+5=20[/tex]
[tex]x-3=20[/tex]
[tex]x=20+3[/tex]
[tex]x=23[/tex]

We can conclude that Susan's weekly allowance is $23

We know that the weekly allowance is the total amount of money that Susan receives weekly before expenses and earns, that is: 
Expenses = $8.00 
Earns = $5.00  
As she ended up with $20.00 we can calculate the weekly allowance as:
 Allowance - Expenses + Earns = Ended-up
 Allowance - 8 + 5 = 20
 Allowance = 20 + 8 - 5 = 23
 
Allowance is $23.00
