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 yellow and blue envelopes sold?
- Each brown envelope cost $0.10 more than each red envelope. The bookshop collected $96 from selling the red envelopes. What was the price of 1 brown envelope?
(a)
Difference between number of yellow and blue envelopes sold
= 41 - 26
= 15
(b)
Number of red envelopes sold = 64
Price of 1 red envelope
= 96 ÷ 64
= $1.50
Price of 1 brown envelope
= 1.50 + 0.10
= $1.60
Answer(s): (a) 15; (b) $1.60
