[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.
