- Each green pencil cost $0.50 more than each grey pencil. The bookshop collected $52 from selling the grey pencils. What was the price of 1 green pencil?
(a)
Difference between number of silver and red pencils sold

(b)
Number of grey pencils sold = 40
Price of 1 grey pencil

Price of 1 green pencil
= 1.30 + 0.50
= $1.80
Answer(s): (a) 44; (b) $1.80
