Response to the following problem:
Sonja Tanner is going to Nepal on a buying trip. She wants to purchase purses, scarves, and hats to import into the United States. Her customers do not want to pay more than $35 for a purse, $25 for a scarf, and $50 for a hat.
Because Sonja would like to keep a markup based on cost of 150%, what is the most she can pay for (a) a purse, (b) a scarf, and (c) a hat?
