Question

Uzupełnij tabelę , wpisująć odpowiednei liczby lub wyrażenia algebraiczne :

Cena netto Stawka VAT Cenna brutto

320 23%

40 8%

a 23%

b 8%

23% 676,50

8% 54

23% c

8% d

Answer 1

Cena brutto = Cena netto * (100%+Stawka VAT)

Cena netto = Cena brutto / (100%+Stawka VAT)

 

Pierwsze 4

320 * (100%+23%) = 320*123% = 320*1,23 = 393,6

40 * (100%+8%) = 40 * 108% = 40*1,08 = 43,2

a * (100%+23%) = a *123% = a*1,23

b *(100%+8%) = b * 108% = b*1,08

 

Ostatnie 4

676,50/(100%+23%)=676,50/123%=676,50/1,23= 550

54/(100%+8%) = 54/108%=54/1,08 = 50

c/(100%+23%)=c/123%=c/1,23

d/(100%+8%) = d/108%=d/1,08

 

Answer 2

Na pewno dobrze to jest, bo to robilismy na lekcji :))

 

320 * (100%+23%) = 320*123% = 320*1,23 = 393,6

40 * (100%+8%) = 40 * 108% = 40*1,08 = 43,2

a * (100%+23%) = a *123% = a*1,23

b *(100%+8%) = b * 108% = b*1,08

 

 

676,50/(100%+23%)=676,50/123%=676,50/1,23= 550

54/(100%+8%) = 54/108%=54/1,08 = 50

c/(100%+23%)=c/123%=c/1,23

d/(100%+8%) = d/108%=d/1,08
