The way to start is to assign a variable to cost or price for apples Celia bought. Work through a transcription of symbolism from all of that.

v, cost of the 12 apples
v/12, PRICE paid per apple;
She sold 10 apples at v%2F12%2B0.20 dollars per apple.

She paid v dollars.
She took revenue of 10%28v%2F12%2B0.2%29.
Her profit was 1 dollar.

highlight%2810%28v%2F12%2B0.20%29-v=1%29.
That means, the difference between revenue and cost is profit. Solving first for v will allow you to compute the price at which she sold her remaining 10 apples.
