generation sorting by age and graphing

[glossymar]

Hi! I am new to this forum, and a novice at Excel. I have a list of ages of people who made purchases from my company each week this year. My boss wants me to make a chart of how many people in each generation made a purchase each week, and a second chart showing the total # of purchases per generation for this year. The Week's date is in the first row, and the ages of the people are in the column below. How can I best sort this data? Thank you so much for any help!!!
