Question: Erwan went on shopping. He purchased a pair of shoes at $200 but discounted 30%, and two shirts at $80 each. Upon checkout, the cashier said that there is an additional 5% discount. How much did he spend after all the discounts?
Answer: The total discount of a pair of shoes is $200 x 30 / 100 = $60. He spent $200 - $60 = $140 for a pair of shoes. The total cost of two shirts is $80 x 2 = $160. The initial cost of his purchase is $140 + $160 = $300. He got an additional $300 x 5 / 100 = $15 discount upon checkout. Therefore, Erwan spent $300 - 15 = $285 after all the discounts. The answer is 285.
Q: John used to buy 4 coffees a day for $2 each. They raised the price by 50% so he cut the number of coffees he drinks in half. How much money does he save per day compared to what he used to spend?
A:
He now buys 4 / 2 = 2 coffees. The new price is 2 * .5 = $1 more than the old price. So he now pays 2 + 1 = $3 per coffee. So he spends 3 * 2 = $6. He used to spend 4 * 2 = $8. So he saves 8 - 6 = $2 per day. The answer is 2.
