The answer is that Ryu saved $17.50
Explanation: Two ways to look at it, 35% is the same as saying 35 hundredths or 0.35. We know that anytime there’s an of in a math problem it means multiply, so you multiply .35x50 and you get 17.5 or $17.50.
Explanation 2: you can look at the 50 as the 100%, so if you divide 100% by 100 you get 1% so that’s what we’re going to start with dividing the 50 by 100 and you get .5, and now that you have 1% you can multiply that by 35 to get the 35%. Which is 17.5
