The bookshop sells 4 different coloured papers. The line graph shows the number of papers sold for each colour in a week.
- What was the difference between the number of blue and gold papers sold?
- Each pink paper cost $0.70 more than each yellow paper. The bookshop collected $72 from selling the yellow papers. What was the price of 1 pink paper?
(a)
Difference between number of blue and gold papers sold
= 90 - 33
= 57
(b)
Number of yellow papers sold = 90
Price of 1 yellow paper
= 72 ÷ 90
= $0.80
Price of 1 pink paper
= 0.80 + 0.70
= $1.50
Answer(s): (a) 57; (b) $1.50
