Answer 1

Explicație pas cu pas:

există bancnote: 1 leu, 5 lei, 10 lei, 20 lei, 50 lei, 100 lei, 200 lei și 500 lei

$2853 = 4 \times 500 + 3 \times 200 + 2 \times 100 + 1 \times 50 + 3 \times 1 = 2000 + 600 + 200 + 50 + 3$

$2853 = 3 \times 500 + 4 \times 200 + 3 \times 100 + 5 \times 50 + 3 \times 1 = 1500 + 800 + 300 + 250 + 3$

$15000 = 20 \times 500 + 19 \times 200 + 10 \times 100 + 2 \times 50 + 4 \times 20 + 20 \times 1 = 10000 + 3800 + 1000 + 100 + 80 + 20$

$15000 = 25 \times 500 + 6 \times 200 + 10 \times 100 + 6 \times 50 = 12500 + 1200 + 1000 + 300$

$100000 = 95 + 500 + 105 \times 200 + 250 \times 100 + 100 \times 50 + 70 \times 20 + 6 \times 10 + 40 \times 1 = 47500 + 21000 + 25000 + 5000 + 1400 + 60 + 40$

$100000 = 76 \times 500 + 157 \times 200 + 88 \times 100 + 318 \times 50 + 285 \times 20 + 200 \times 1 = 38000 + 31400 + 8800 + 15900 + 5700 + 200$

există monede: 50 de bani = 0,5 lei, 10 bani = 0,1 lei, 5 bani = 0,05 lei, 1 ban = 0,01 lei

$5 = 8 \times 0.5 + 8 \times 0.1 + 3 \times 0.05 + 5 \times 0.01 = 4 + 0.8 + 0.15 + 0.05$

$10 = 18 \times 0.5 + 6 \times 0.1 + 6 \times 0.05 + 10 \times 0.01 = 9 + 0.6 + 0.3 + 0.1$

$25 = 32 \times 0.5 + 50 \times 0.1 + 58 \times 0.05 + 110 \times 0.01 = 16 + 5 + 2.9 + 1.1$
