Question

question a one day ticket to a museum park cost $20 plus $1.03 in sales tax I need to find out what is the tax rate.have I set up the equation correctly at the top 

Answer 1

You have set up, correctly, the STATED relationship (equation) and you wish to solve for tax rate.

 

To isolate tax rate, divide each side of your equation by purchase price,

 

This will be the correct solution, provided your assertion that each purchaser pays $21.03 to obtain a ticket is correct.

In my experience usually such things are priced at $20, INCLUDING $1.03 sales tax--and that's a different problem!
