The first option is to receive a base salary of $300 a week plus 10% of the price of the merchandise he sells. The second option is a base salary of $220 a week plus 18% of the price of the merchandise he sells. The average phone sells for $200, but accessories are also included in the merchandise sales. Which of these two options should Finn choose and why? Finn’s boss has agreed to give him a third salary option. This option includes a base salary of $160 plus 20% of the amount of merchandise he sells. Should Finn take the new offer? Why or why not?
