Question 5

= = = 0,695 x 100 = 69,5%[pic 15][pic 16][pic 17]

Question 6

100% - 2.5% = 97.5%

97.5% x 45 920 = x 45 920 = 447.42[pic 18]

2.5% x 45 920 = 1148[pic 19]

Question 7

1800$ x 4.5% = 1800$ x = 18 x 4.5 = 81$ par année[pic 20]

81 ÷ 4 mois = 20.25$

Question 8

- 62 000$ x 5,5% = 62 000$ x = 620 x 5,5 = 3 410$ = 3 410$ x 4 = 13 640$ pour 4 ans[pic 21]

- 3 410$ x 48% = 3 410$ x = 34,10$ x 48 = 1636,80$/an[pic 22]

- 3410$ - 1636,80$ = 1773,20$
