For (b), we know $9 for every 4 CDs, so $90 for 40 CDs. $2.80 for 1 CD. Altogether 41 CDs.

Box C has 6 less than Box B and 20 less than Box A. Hence, Box B has 14 less than Box A. 1 unit ＝ 14 Box C will have 14-6＝8 beads..

Number of dresses given away ＝ 4 x 21 ＝ 84 3 wardrobes ＝ 84 1 wardrobe ＝84/3 ＝28 4 wardrobes ＝ 4x28＝112

becos if total no of dress left equals to no of dress in 1 wardrobe, then total no of dresses given away equals to no of dresses in 3 wardrobes

Draw 4 equal bars to represent the number of dresses in each wardrobes. Total number = 4 units 4 units - 84 = 1 unit Therefore 1 unit = 28 Total number = 4 units = 112
