There are six times as many white sweaters as blue sweaters in a sale. If there are 189 white and blue sweaters altogether,
- how many white sweaters are there?
- how many more white sweaters than blue sweaters?
(a)
Number of blue sweaters = 1 u
Number of white sweaters
= 6 x 1 u
= 6 u
Total number of sweaters
= 6 u + 1 u
= 7 u
7 u = 189
1 u = 189 ÷ 7 = 27
Number of white sweaters
= 6 u
= 6 x 27
= 162
(b)
Number of more white sweaters than blue sweaters
= 6 u - 1 u
= 5 u
= 5 x 27
= 135
Answer(s): (a) 162; (b) 135
