The bookshop sells 4 different coloured markers. The line graph shows the number of markers sold for each colour in a week.
- What was the difference between the number of silver and purple markers sold?
- Each brown marker cost $0.60 more than each pink marker. The bookshop collected $88 from selling the pink markers. What was the price of 1 brown marker?
(a)
Difference between number of silver and purple markers sold
= 68 - 25
= 43
(b)
Number of pink markers sold = 10
Price of 1 pink marker
= 88 ÷ 10
= $8.80
Price of 1 brown marker
= 8.80 + 0.60
= $9.40
Answer(s): (a) 43; (b) $9.40
