Goodmorning all help me guys​

Answer 1

Answer:

Step-by-step explanation:

Profit = Yield -  labor expenses -  fertilizer expenses

         $=\frac{100p + 200}{2p} - \frac{10p+20}{3p} - \frac{5p-10}{p}\\\\=\frac{(100p + 200)*3}{2p*3} - \frac{(10p+20)*2}{3p*2} - \frac{(5p-10)*6}{p*6}\\\\=\frac{300p + 600}{6p} - \frac{20p+40}{6p} - \frac{30p-60}{6p}\\\\= \frac{300p+600 - (20p+40) - (30p-60)}{6p}\\\\= \frac{300p+600-20p-40-30p+60}{6p}\\\\=\frac{300p-20p-30p+600-40+60}{6p}\\\\=\frac{250p+620}{6p}$
