Question: On her birthday, Avianna bought red candles and blue candles in the ratio of 5:3. If Avianna had 45 red candles on her birthday, how many blue candles did she have?
Answer: If the ratio of red candles to blue candles Avianna bought was 5:3, then the total ratio was 5 + 3 = 8. If 5 represented 45 candles in the total ratio, then 8, the actual ratio, represents 8 * 45 = 360 divided by 5 is 360 / 5 = 72 candles. If the total number of candles was 72, then the number of blue candles is 72 candles - 45 candles = 27 candles. The answer is 27.

Q: Celina enjoys hiking in the mountains. Due to a lack of proper equipment, she decided to order a new pair of boots, a flashlight, and a special hoodie. The hoodie cost $80 and the flashlight was only 20% of that price. The pair of boots cost was $110, but due to a special promotion, Celina was able to buy them 10% cheaper. How much did Celina spend in total on the above-mentioned equipment?
A: The flashlight was 20% of the price of the hoodie, so 80 * 20 / 100 = $16. The promotion for a pair of boots was 110 * 10 / 100 = $11. So the pair of boots cost 110 - 11 = $99. Celina therefore spent 80 + 16 + 99 = $195 on the equipment. The answer is 195.
