For this case, the first thing we must do is define a variable.
 We have then:
 x: the number of donuts Lee you have purchased
 In the morning we have:
 2x
 In the afternoon we have:
 x
 Therefore, the total amount that Lee buys is:
 2x + x
 Answer:
 an expression that represents these purchases is:
 2x + x
