There are four times as many pink shirts as white shirts in a sale. If there are 130 pink and white shirts altogether,
- how many pink shirts are there?
- how many more pink shirts than white shirts?
(a)
Number of white shirts = 1 u
Number of pink shirts
= 4 x 1 u
= 4 u
Total number of shirts
= 4 u + 1 u
= 5 u
5 u = 130
1 u = 130 ÷ 5 = 26
Number of pink shirts
= 4 u
= 4 x 26
= 104
(b)
Number of more pink shirts than white shirts
= 4 u - 1 u
= 3 u
= 3 x 26
= 78
Answer(s): (a) 104; (b) 78
