Question

retire do valor 320 as porcentagens de 3%,18%,50% e 4% Quanto vai sobrar? com calculo por favor

Answer 1

x=320*(100-0,03+0,18+0,50+0,04)

x=320*0,25

x=80

Resposta: Vai sobrar 80

Answer 2

320----------100%

x--------------3%

100x = 320 . 100

100x = 960

x = 960/100

x = 9,6

320 - 9,6 = 310,40

310,40-----------100%

x-------------------18%

100x = 310,40 . 18

100x = 5587,2

x = 5587,2/100

X = 55,872

310,40 - 55,782 = 254,528

254,528--------------100%

x------------------------50%

100x = 254,528 . 50

100x = 12726,4

x = 12726,4/100

x = 127,264

254,528 - 127,264 = 127,264

127,264---------100

x------------------4%

100x = 127,264 . 4

100x = 509,056

x = 509,056/100

x = 5,09056

127,264 - 5,09056 = 122,17344

Então sobra 122,17344
