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 yellow pencils sold?
- Each white pencil cost $0.40 more than each pink pencil. The bookshop collected $63 from selling the pink pencils. What was the price of 1 white pencil?
(a)
Difference between number of gold and yellow pencils sold
= 89 - 64
= 25
(b)
Number of pink pencils sold = 45
Price of 1 pink pencil
= 63 ÷ 45
= $1.40
Price of 1 white pencil
= 1.40 + 0.40
= $1.80
Answer(s): (a) 25; (b) $1.80
