A guitar originally costs $600, but it is on sale for 45% off. If a customer buying the guitar has a coupon for $30.00 off of any purchase, what will her final price be on the guitar?

With the 45% off sale, the guitar price would be deducted by $270, which would result in it being $330.

And with the $30 coupon, the final price, not including tax, would be $300,

600 • 0.45 = 330

330 - 30 = 300
