Wow! Thank you. I figured out I was looking for the percent of $90 he WOULD save not how much he DID save after I posted my question hehe. Which is why I was so confused, also, my teacher gave like a hint sheet that asked what percent he saved... So I was pretty confused haha. But thanks for taking the time to make a video lol :) I can get an A in trig, but can't do simple % problems lol... I always over think things haha
