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

2,50xp/100==2,95
p=(2,95x100)/2,50
p=118
tva reprezinta 18 %

verificare: 2,50x18/100=0,45
2,50+0,45=2,95 lei

Answer 2

[tex]\sf 2,50+ \frac{2,50x}{100}=2,95 \\ \\ \frac{250}{100}+ \frac{2,50x}{100}= \frac{295}{100}|*100 \\ \\ 250+2,50x=295 \\ \\ 2,50x=295-250 \\ \\ 2,50x=45 \\ \\ \boxed{\sf x=18 \%} [/tex]
