If 20% remain, only 80% were sold.
M = cookies Matt made
1.25M = cookies Phil make
E = earnings
E = 0.80[0.25M + 0.25(1.25M)]
E = 0.80[0.25M + 0.3125M]
E = 0.80[0.5625M]
E = 0.45M

Phil made 25% more that Matt.
So Phil made what Matt made plus 0.25.

If Phil and Matt made a total of $72 selling the cookies, how many cookies did each Phil and Matt make?

E = 0.45M
72 = 0.45M
160 = M
Matt sold 160 cookies and Phil sold 200 cookies.

I still don't understand where the 1.25 comes from. We don't know what Matt made because you said phil made what matt made plus .25

Did you add the 20% plus 80% and add the 25 percent more Phil made?

Phil sells what Matt sells, M, plus 25%, or 0.25 more, or M + 0.25M = 1.25M
