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 green and brown pencils sold?
- Each pink pencil cost $0.60 more than each yellow pencil. The bookshop collected $77 from selling the yellow pencils. What was the price of 1 pink pencil?
(a)
Difference between number of green and brown pencils sold
= 34 - 24
= 10
(b)
Number of yellow pencils sold = 10
Price of 1 yellow pencil
= 77 ÷ 10
= $7.70
Price of 1 pink pencil
= 7.70 + 0.60
= $8.30
Answer(s): (a) 10; (b) $8.30
