*40*

Female 50

*20*

**20**

b) What percent of those surveyed preferred regular coffee?

i have .3%

c) What percent of females preferred bold?

i have .2222%

d) What percent of those that preferred bold were female?

3.5 %

e) A buyer for Dunkin’ Donuts reviewed the table above. If she were to base her

purchase of 1000 pounds of coffee on that information, how much of each type

of coffee – mild, regular, and bold – should she buy? Explain your answer.

So far I have: she should be 35% mld and bold which equals 70%. and 30% regular. 350 pounds of mild, 350 pounds of bold, and 300 pounds of regular.
