Mila owns a health-food store in a city close to where Anna lives. Mila is always so welcoming and helpful when Anna shops at the store that Anna is considering interviewing Mila about her career. Anna wants to know why Mila chose to work in retail.

 

Anna has just dropped into the store to buy some 500-mg tablets of vitamin C. Anna holds up two containers of tablets. “It costs $8.99 for 200 tablets and $18.99 for 500 tablets. Which container is the better buy?” Anna asks.

 

“Generally, the larger size is less expensive,” Mila says, “but not always!” Bring the containers to the counter, and I’ll use my calculator to check. Also think about whether you would use all 500 tablets before they expire.”

 

Which container would you buy?
