Answer:
Explanation:
In total, you spent 21$ and you already know that you spent 12$ on chicken, so first you would take 21 and subtract it by 12 resulting in 9.
So if you bought 6 peppers, you would divide the 9 dollars you spent in total on peppers and divide it by 6 resulting in 1.5$ so you spent 1.5$ on each pepper or 1 dollar and 50 cents.
Simpler terms:
21$-12$=9$
9$/6$=1.50$
1 Dollar and 50 Cents Per Pepper
