4 dress shirts cost $15.00 each so 4*15 = $<<4*15=60.00>>60.00
2 pants at $40.00 cost 2*40 = $<<2*40=80.00>>80.00
2 sweaters at $30.00 cost 2*30 = $<<2*30=60.00>>60.00
Add the suit at $150 and the other items the total was 150+60+80+60 = $<<150+60+80+60=350>>350
The store has having a 20% off sale so .20*350 = $<<350*.20=70.00>>70.00 discount
His new total would be 350-70 = $<<350-70=280.00>>280.00
Then add his 10% discount, .10*280= $<<28=28.00>>28.00 additional off
His final total came out to 280-28 = $<<280-28=252.00>>252.00
