Answer 1

Profit =
`(80p + 170)/(p)`

Explanation:

Cost of the Yield =
`(100p + 200)/(p)`

Cost of the labour =
`(10p + 50)/(p)`

Cost of the fertilisers =
`(10p - 20)/(p)`

Total expenses =
`(10p + 50)/(p) + (10p - 20)/(p) = (20p + 30)/(p)`

Profit = Total expenses - Cost of yield

`= > (100p + 200)/(p) - (20p + 30)/(p)`

`= > (80p + 170)/(p)`
