There are four times as many blue vests as silver vests in a sale. If there are 135 blue and silver vests altogether,
- how many blue vests are there?
- how many more blue vests than silver vests?
(a)
Number of silver vests = 1 u
Number of blue vests
= 4 x 1 u
= 4 u
Total number of vests
= 4 u + 1 u
= 5 u
5 u = 135
1 u = 135 ÷ 5 = 27
Number of blue vests
= 4 u
= 4 x 27
= 108
(b)
Number of more blue vests than silver vests
= 4 u - 1 u
= 3 u
= 3 x 27
= 81
Answer(s): (a) 108; (b) 81
