There are four times as many yellow blazers as white blazers in a sale. If there are 180 yellow and white blazers altogether,
- how many yellow blazers are there?
- how many more yellow blazers than white blazers?
(a)
Number of white blazers = 1 u
Number of yellow blazers
= 4 x 1 u
= 4 u
Total number of blazers
= 4 u + 1 u
= 5 u
5 u = 180
1 u = 180 ÷ 5 = 36
Number of yellow blazers
= 4 u
= 4 x 36
= 144
(b)
Number of more yellow blazers than white blazers
= 4 u - 1 u
= 3 u
= 3 x 36
= 108
Answer(s): (a) 144; (b) 108
