The total sales is #=400000$#

The basic salary is #B=15000$#

The total for the month of March is #T=25000$#

The comission is

#C=T-B=(25000-15000)$=10000$#

The commission is

#{(1% if S=100000-250000$),(5%ifS>250000$):}#

#1%# of #250000# is #=250000/100=2500#

Therefore,

The sales are #>250000$#

Therefore,

If the sales is #S# above #250000$#

The commission is

#S*5/100=10000-2500#

#S=7500*100/5=15000#

The total sales is

#=250000+150000=400000$#
