A sports shop had 400 cricket balls for sale. Each cricket ball is sold at $5. At the end of each day, the number of cricket balls sold was recorded in the bar graph shown.
- What fraction of the total number of cricket balls was left at the end of Day 3? Express your answer in its simplest form.
- If the shop decided to sell every 6 cricket balls at $26 from Day 4 onwards, how much less would it collect from the sale of the cricket balls?
(a)
Number of cricket balls left at the end of Day 3
= 400 - 96 - 108 - 72
= 124
Fraction of cricket balls left at the end of Day 3
=
124400=
31100 (b)
Number of cricket balls sold from Day 4 to Day 6
= 102 + 108 + 90
= 300
Amount that it would collect if it sold the 300 cricket balls at the original price
= 300 x 5
= $1500
Number of sets of 6 cricket balls
= 300 ÷ 6
= 50
Amount that it would collect if it sold the 300 cricket balls at every 6 cricket balls at $26
= 50 x 26
= $1300
Amount that it would collect less from the sale of the cricket balls
= 1500 - 1300
= $200
Answer(s): (a)
31100; (b) $200
