A sports shop had 500 cricket balls for sale. Each cricket ball is sold at $2. 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 3 cricket balls at $4 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
= 500 - 48 - 48 - 39
= 365
Fraction of cricket balls left at the end of Day 3
=
365500=
73100 (b)
Number of cricket balls sold from Day 4 to Day 6
= 33 + 33 + 57
= 123
Amount that it would collect if it sold the 123 cricket balls at the original price
= 123 x 2
= $246
Number of sets of 3 cricket balls
= 123 ÷ 3
= 41
Amount that it would collect if it sold the 123 cricket balls at every 3 cricket balls at $4
= 41 x 4
= $164
Amount that it would collect less from the sale of the cricket balls
= 246 - 164
= $82
Answer(s): (a)
73100; (b) $82
