運動褲原價每條153元，運動鞋每對542元，現在運動褲每條減25元，爸爸付一張1000元買三條褲一對鞋找回多少元?


1000 - ( 135 x 3 - 25 x 3 + 542 )

=1000 - ( 415 - 75 + 542 )

=1000 -340 + 542

= 882

找$74$ ${}$

1000-[(153-25)*3+542]
=1000-[128*3+542]
=1000-[384+542]
=1000-926
=74

1000 - ( (153-25)x3 + 542)
=1000 - 926
=74

1000-(153-25)x3=74

1000-(153-25x3)+542=74

共要付錢=(153-25)x3+542
=$926
找回=1000-926
=$74

1000-(153-25)x3+542 = 74

1000-{542+(153-25)x3} =74元
