I am working on a project for a managerial accounting class. I am supposed to create a contribution quarterly projected income statement. However, I was provided with baseline check figures for the final answers and they don't match what I got from my computations. I have attached an image of the provided data and what I have so far.

My answer $-$ $$1,250,625-$ actual answer $-$ $$757,763$

My answer $-$ $$39,262-$ actual answer $-$ $$5,898$

My answer$-$ $$1,211,362-$actual answer $-$ $$751,864$

What am I doing wrong?
