The bookshop sells 4 different coloured envelopes. The line graph shows the number of envelopes sold for each colour in a week.
- What was the difference between the number of red and pink envelopes sold?
- Each purple envelope cost $0.30 more than each silver envelope. The bookshop collected $55 from selling the silver envelopes. What was the price of 1 purple envelope?
(a)
Difference between number of red and pink envelopes sold
= 56 - 50
= 6
(b)
Number of silver envelopes sold = 25
Price of 1 silver envelope
= 55 ÷ 25
= $2.20
Price of 1 purple envelope
= 2.20 + 0.30
= $2.50
Answer(s): (a) 6; (b) $2.50
