Question

Un produs costa 1900 lei. Aflati pretul produsului dupa doua scumpiri consecutive cu 10% fiecare

Answer 1

prima scumpire:
1900+1900*10/100=1900+19*10=1900+190=2090 pretul dupa prima scumpire

a doua scumpire
2090+10*2090/100=2090+209=2299 pretul dupa a doua scumpire

Answer 2

Prima scumpire:
$\frac{110}{100}$×1900=110×19=2090 (lei)

A doua scumpire:
$\frac{110}{100}$×2090=11×209=2299 (lei)

Dupa doua scumpiri consecutive, produsul costa 2299 lei...
