Solve without a calculator log_5(240)-log_5(75)-log_5(80)

Log₅ 240-log₅75-log₅ 80=
log₅ (240/75)-log₅ 80=                      (log_a b- log_a c=log_a (b/c) )
:log₅3.2 - log₅80=                            
log₅(3.2/80)=                                    (log_a b- log_a c=log_a (b/c) )  
log₅0.04=
log₅ 4/100=
log₅ 1/25=
log₅ 1 - log₅ 25=                                (log_a 1=0)
0-log₅25=
-log₅25=
-log₅5²=x    ⇔ x=-2                            (log_a a^n=n)

log₅ 240-log₅75-log₅ 80=-2

The answer is d. 606 because you have to multiply 30% ( percent) times 2020 (total) to get ur answer.
