13. Solution:
2 fifths of 20-cent coins + 3 sevenths of 50-cent coins  39 coins
4 fifths of 20-cent coins + 6 sevenths of 50-cent coins  2 x 39 coins = 78 coins
1 fifth of 20-cent coins + 1 sevenths of 50-cent coins  94 – 78 = 16
5 fifths of 20-cent coins + 5 sevenths of 50-cent coins  5 x 16 = 80
2 sevenths of 50-cent coins  94 – 80 = 14
There are 14 2 x 7 = 49 fifty-cent coins.
There are 94 – 49 = 45 twenty-cent coins.
Sally had 49 x 50 cents + 45 x 20 cents or $33.50.
Answer:$33.50

17. 94 – 2 x 39 = 94 – 78 = 14 + 2 = 16

18. 94 – 2 x 39 = 94 – 78 = 14 + 2 = 16

19. 94 – 2 x 39 = 94 – 78 = 14 + 2 = 16

20. ?
94 – 2 x 39 = 94 – 78 = 14 + 2 = 16

21. ?
94 – 2 x 39 = 94 – 78 = 14 + 2 = 16
39 – 2 x 16 = 39 – 32 = 7
How many 50-cent coins?
How many 20-cent coins?

29. Solution:
(a) (3m + 6) cm
(b) length = 3 x 4 cm + 6 cm = 18 cm and width = 3 cm
area = 18 cm x 3 cm = 54 cm2

32. 9 parts 6 parts 5 parts $120  16 parts
$30  4 parts
$150  20 parts
He had $150 at first.

34. men
women
837 – 648 = 837 – 637 – 11 = 200 – 11 = 189
1 third of the men + 1 third of the children  189
men + children  189 x 3 = 570 – 3 = 567
women  837 – 567 = 837 – 537 – 30 = 270
men  270 3 x 4 = 90 x 4 = 360
children  837 – 360 – 270 = 837 – 630 = 207
There were 207 children at first.
