Question

A hotel manager found that his gross receipts for the? day, including a 7?% sales? tax, were ?$3122.26

Find the amount of sales tax collected.

 

What was the sales? tax?

Answer 1

To compute the sales tax, let x = the gross receipts (not including tax)

 

(1 + 0.07)x = 3122.26

 

1.07x = 3122.26

 

x = $2,918 (the total receipts minus tax)

 

To find the sales tax collected, subtract

 

3122.26 - 2918 = $204.26
