Answer Key

1) a) 36



b) 9










2) Total : 139.8kg


Average = 139.8 ÷ 4 = 34.95kg


3) Total = 378.10

Average = 378.10 ÷ 5 = $75.62



4) Average = 645.7 litres ÷ 8 = 80.7125 » 80.7 litres



5) Perimeter = 14.8 x 4 = 59.2m



6)
7)


Total score = 92 x 4 = 368


A + B + C + D = 368

78 + 95 + 88 + D = 368


D = 368 - 78 - 95 - 88 = 107 points

8)

9)

10) a) 28% b) 72%

11) a) 67 b) 9/100 c) 9/50 d) 13/25

12) a) 47% b) 70%

c) 10% d) 77%

e) 7% f) 70%

13) 57 out of 100 = 57/100 = 57% = 0.57

3 out of 10 = 3 /10 = 30% = 0.3

14) a) 44% b) 90%

c) 51% d) 36%

15) a) 65% b) 64%

16) 100% - 82% = 18%

18% x 950 = 80/100 x 950 = 171 seats not occupied.

17)

100% - 30% - 28% = 42% --> 50cent coins

42% x $50 = 42/100 x $50 = $21

18)

19)

GST = 7% x $860 = $60.20

Total paid = GST + Price = $60.20 + 860 = $920.20

20)

Discount = 35%

Discounted price = 100% - 35% = 65%

Amount paid = 65% x 725.60 = $471.64

21)

Discounted price = 100% - 15% = 85%

Amount after discount = 85% x 4505 = $3829.25

Downpayment = 4% x 3829.25 = $153.17
