Hi, I'm not too good with taxes and discounts and everything. I am a little lost in this exercise:
Marie-Christine wants to buy a sweater at $ 42.50, pants at $ 55.25 and a pair of shoes at $ 79.75. Today, the store is offering a 40% discount for any purchase over $ 100. How much will she have to pay if a 15% tax is applied to her purchases?
