Question

O barca costa 2500 euro. Cat costa dupa o scumpire de 3%? Dar dupa o ieftinire de 3%?

Answer 1

SCUMPIREA:

$100\% + 3\% = 103\% \\ \frac{103}{100} \times 2500 = \frac{103 \times 2500}{100} = 103 \times 25 = 2575$
IEFTINIREA:

$100\% - 3\% = 97\% \\ \frac{97}{100} \times 2500 = \frac{97 \times 2500}{100} = 97 \times 25 = 2425$

Answer 2

cred ca 2456 si 25y77
