Question

Un kilogram de banane fara T.V.A costa 2.50 lei, iar cu T.V.A costa 2.95 lei. Cat la suta reprezinta T.V.A.-ul?

Answer 1

ai o greseala la enunt..........dar incerc sa=ti raspund dupa cum inteleg eu
a= pretul fara TVA

a + ax b% = 2,95
2,5 x( 1+ b/100 ) =  2,95
1+b/100 = 2,95/2,5
b/100 = 1,18 - 1
b/100 = 0,18

b= 18

Answer 2

x=TVA
2.50 lei plus $\frac{x}{100}$·2.50 lei = 2.95
x/100·2.50= 2,95-2,50
x/100·2.50= 0.45
x/100= 0,45:2,50
x/100=45:250
x/100=0,18
x=0.18 · 100
x=18%
