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 blue and white pencils sold?
- Each pink pencil cost $0.30 more than each red pencil. The bookshop collected $69 from selling the red pencils. What was the price of 1 pink pencil?
(a)
Difference between number of blue and white pencils sold
= 64 - 37
= 27
(b)
Number of red pencils sold = 46
Price of 1 red pencil
= 69 ÷ 46
= $1.50
Price of 1 pink pencil
= 1.50 + 0.30
= $1.80
Answer(s): (a) 27; (b) $1.80
