1st ring=$50
2nd ring=$37.50
3rd ring=$25
$50+$37.50+$25 =$112.50 total cost before tax
$112.50 X 1.08=$121.5 total cost and tax
3 X $50 X 1.08=$162 total cost without discount deal
$162 - $121.50 =$40.50 savings

TanY=y/x
cotY=1/tanY
cotY=x/y
Answer:
The answer is A) Round 56 to 60, find 10%, then double.
Step-by-step explanation:
You would round to 60 because 56 is closer to 60 than 50 then 10% is half of 20% so you would double it after you found 10% of 60.
Hope this helps :)
