There are four times as many purple shirts as pink shirts in a sale. If there are 105 purple and pink shirts altogether,
- how many purple shirts are there?
- how many more purple shirts than pink shirts?
(a)
Number of pink shirts = 1 u
Number of purple shirts
= 4 x 1 u
= 4 u
Total number of shirts
= 4 u + 1 u
= 5 u
5 u = 105
1 u = 105 ÷ 5 = 21
Number of purple shirts
= 4 u
= 4 x 21
= 84
(b)
Number of more purple shirts than pink shirts
= 4 u - 1 u
= 3 u
= 3 x 21
= 63
Answer(s): (a) 84; (b) 63
