There are four times as many yellow jackets as silver jackets in a sale. If there are 140 yellow and silver jackets altogether,
- how many yellow jackets are there?
- how many more yellow jackets than silver jackets?
(a)
Number of silver jackets = 1 u
Number of yellow jackets
= 4 x 1 u
= 4 u
Total number of jackets
= 4 u + 1 u
= 5 u
5 u = 140
1 u = 140 ÷ 5 = 28
Number of yellow jackets
= 4 u
= 4 x 28
= 112
(b)
Number of more yellow jackets than silver jackets
= 4 u - 1 u
= 3 u
= 3 x 28
= 84
Answer(s): (a) 112; (b) 84
