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 silver and gold pencils sold?
- Each green pencil cost $0.50 more than each pink pencil. The bookshop collected $88 from selling the pink pencils. What was the price of 1 green pencil?
(a)
Difference between number of silver and gold pencils sold
= 50 - 23
= 27
(b)
Number of pink pencils sold = 20
Price of 1 pink pencil
= 88 ÷ 20
= $4.40
Price of 1 green pencil
= 4.40 + 0.50
= $4.90
Answer(s): (a) 27; (b) $4.90
