Solutions to Math Problems
1.
| Weft Thread | = 8m + 17m
= 25m |
| Silk Thread | = 21m + 17m
= 38m |
| Total Thread | = 21m + 8m + 17m
= (46) m |
2. Eight cowrie shells cost = 8 x $0.75
8 x 0.75 = 6.00
Two dozen Abalone shell rounds = 2 x $2.00 = $4.00
Four starfish cost = 4 x $1.00 = $4.00
Total cost = $6.00 + $4.00 + $4.00 = $14.00
Change = $20.00 - $14.00 = $6.00
3.
Upper region: 12 x 21 = 252
Lower region: 8 x 14 = 112
Total = 252 + 112 = 364 sequins
Top = 21 x 1/4 inch = 5-1/4 inches
Left side = 12 x 1/4 inch = 3 inches
4.
Number of red beads
Number of green beads
Number of blue beads
Number of brown beads
|
= 1/3 x 3600 = 1200
= 1/4 x 3600 = 900
= 1/6 x 3600 = 600
= 3600 - 1200 - 900 - 600
= 2400 - 900 - 600
= 1500 - 600
= 900

Cost of the red beads
Cost of the green beads
Cost of the blue beads
Cost of the brown beads
|
= 1200 x $.02
= 900 x $.03
= 600 x $.01
= 900 x $.005
|
= $24.00
= $27.00
= $6.00
= $4.50
|
| Total Cost
|
= $24.00 + $27.00 + $6.00 + $4.50
= $51.00+ $6.00 + $4.50
= $57.00 + $4.50
= $61.50
