Q: Henley bought 300 candies and shared them with her two brothers. However, they realized 40% of them were sour, and they had to separate those out. If they then shared the good candies equally, how many candies did each get?
A: If the number of candies was 300, and 40% percent were sour, then there were 40 / 100 * 300 = 120 sour candies. The number of good candies was 300 - 120 = 180. The number of people who received candy is Henley, 1 + 2 brothers = 3 people. if they divided the good candies equally, each person got 180 / 3 = 60 candies. The answer is 60.
Question: Silvia wants to buy a new guitar online. The price of the guitar has a suggested retail price of $1000. Guitar Center has a special deal of 15% off but has a shipping fee of $100. Sweetwater has a 10% off deal with free shipping. How much will she save by buying from the cheaper store compared to the other store?
Answer: The discount saved when buying from Guitar Center would be $1000 * 15% = $150. The total cost when buying from Guitar Center would be $1000 - $150 discount + $100 shipping = $950. The discount when buying from Sweetwater would be $1000 * 10% = $100. The total cost when buying from Sweetwater would be $1000 - $100 discount + $0 shipping = $900. Thus, Silvia would save $950 - $900 = $50 when buying from Sweetwater. The answer is 50.
