The bookshop sells 4 different coloured pencils. The line graph shows the number of pencils sold for each colour in a week.
- What was the difference between the number of gold and brown pencils sold?
- Each green pencil cost $0.70 more than each blue pencil. The bookshop collected $90 from selling the blue pencils. What was the price of 1 green pencil?
(a)
Difference between number of gold and brown pencils sold
= 63 - 26

(b)
Number of blue pencils sold = 12
Price of 1 blue pencil

Price of 1 green pencil
= 7.50 + 0.70
= $8.20
Answer(s): (a) 37; (b) $8.20
