(4m-p)^n

Can someone expand these binomials without using the binomial theorem.

Let’s say they do make an average of $79.35 every bake sale. They’re planning to have 4 more sales so 4x79.35=317.4 which is what they will hypothetically make at the next sales. Add the previous earnings: 79.35+317.4=396.75 and that is the estimated profit for all 5 bake sales which proves that Peggy is correct.
