Michael bought a guitar that was on sale for 15% off the regular price of $200. The total cost included 8% sales tax. What was the total cost?

$183.60

Step-by-step explanation:

Take the regular price and find the 15% discount:

200 x 0.15 = 30

Subtract the discounted amount from the original price:

200 - 30 = 170

Take the new price and find the sales tax:

170 x 0.08 = 13.60

Add the sales tax to the discounted price:

170 + 13.60 = 183.60

if x decreases by 4 then y increases by 10
