There are six times as many brown jackets as blue jackets in a sale. If there are 140 brown and blue jackets altogether,
- how many brown jackets are there?
- how many more brown jackets than blue jackets?
(a)
Number of blue jackets = 1 u
Number of brown jackets
= 6 x 1 u
= 6 u
Total number of jackets
= 6 u + 1 u
= 7 u
7 u = 140
1 u = 140 ÷ 7 = 20
Number of brown jackets
= 6 u
= 6 x 20
= 120
(b)
Number of more brown jackets than blue jackets
= 6 u - 1 u
= 5 u
= 5 x 20
= 100
Answer(s): (a) 120; (b) 100
