There are four times as many pink jumpsuits as purple jumpsuits in a sale. If there are 145 pink and purple jumpsuits altogether,
- how many pink jumpsuits are there?
- how many more pink jumpsuits than purple jumpsuits?
(a)
Number of purple jumpsuits = 1 u
Number of pink jumpsuits
= 4 x 1 u
= 4 u
Total number of jumpsuits
= 4 u + 1 u
= 5 u
5 u = 145
1 u = 145 ÷ 5 = 29
Number of pink jumpsuits
= 4 u
= 4 x 29
= 116
(b)
Number of more pink jumpsuits than purple jumpsuits
= 4 u - 1 u
= 3 u
= 3 x 29
= 87
Answer(s): (a) 116; (b) 87
