NEED HELP ASAP! Carolina and Patricia received their Christmas bonus and decided to use this weekend to buy their Christmas gifts .

Carolina decided to take advantage of the Great Winter Sale in Liverpool that offers discounts of 50% + 20%.

Patricia went to the mall and took advantage of the boutique discount that offers discounts of 70%.

They both bought 3 items with a total listing price of $120. At the end of their purchase rounds, they will have coffee with their friend Cristina and tell her about the offers they found. Based on their experiences, Cristina must decide where she will do her shopping.

Analyze this situation and think,

Where would you recommend Cristina to do her shopping? What is the final price paid on each establishment?
