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 white and gold markers sold?
- Each purple marker cost $0.40 more than each silver marker. The bookshop collected $96 from selling the silver markers. What was the price of 1 purple marker?
(a)
Difference between number of white and gold markers sold
= 68 - 62
= 6
(b)
Number of silver markers sold = 20
Price of 1 silver marker
= 96 ÷ 20
= $4.80
Price of 1 purple marker
= 4.80 + 0.40
= $5.20
Answer(s): (a) 6; (b) $5.20
