Answer:


A=400\ people

Explanation:

we have


Q=600+√(A+41)

where

Q -----> is the daily output

A -----> is the number of people

For Q=621

Find the value of A

substitute and solve for A


621=600+√(A+41)

Subtract 600 both sides


621-600=√(A+41)


21=√(A+41)

squared both sides


21^(2) ={A+41}


441={A+41}

Subtract 41 both sides


441-41=A

Rewrite


A=400\ people
