[Question]A smartphone seller is offering a discount of 5% off for customers who buy at least 2 smartphones at once. Melinda, Zoe and Joel want to buy an iPhone X each. If an iPhone X costs $600, how much can they save by pooling their money together and buying three iPhones at once from this seller rather than buying individually?
[Answer]Each iPhone X cost $600 so three iPhone Xs without the discount would cost 3 * $600 = $1800. The discount is 5% and 5% of $1800 is (5 / 100) * $1800 = $90 which is what they get to save by buying collectively. The answer is 90.
