• Sateen.
• Calico.
• Poplin.
• Muslin
• Flannel

(c) The cost of making one blouse is GHC 2.50. Work out the cost of fifteen blouses.
Cost for one blouse = GHC 2.50
Hence, cost for fifteen blouses = 15 x GHC 2.50
= GHC 37.50

(d) If Afua sells one blouse at GHC 3.75. Work out the total profit for the fifteen blouses

Profit = Selling price – Cost price
Profit for 1 blouse = GHC 3.75 – GHC 2.50
= GHC 1.25
Hence, profit for 15 blouses = 15 x 1.25
= GHC 18.75

2ND METHOD

If selling price for 1 blouse = GHC 3.75
Then, selling price for 15 blouses = 15 x GHC 3.75
= GHC 56.25
Hence, Profit for 15 blouses = Selling price – Cost price
= GHC 56.25 – GHC 37.50
= GHC 18.75
