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 red and gold pencils sold?
- Each brown pencil cost $0.20 more than each pink pencil. The bookshop collected $62 from selling the pink pencils. What was the price of 1 brown pencil?
(a)
Difference between number of red and gold pencils sold
= 36 - 14
= 22
(b)
Number of pink pencils sold = 10
Price of 1 pink pencil
= 62 ÷ 10
= $6.20
Price of 1 brown pencil
= 6.20 + 0.20
= $6.40
Answer(s): (a) 22; (b) $6.40
