A sports shop had 350 cricket balls for sale. Each cricket ball is sold at $4. 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 $19 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
= 350 - 96 - 72 - 78
= 104
Fraction of cricket balls left at the end of Day 3
=
104350=
52175 (b)
Number of cricket balls sold from Day 4 to Day 6
= 78 + 84 + 102
= 264
Amount that it would collect if it sold the 264 cricket balls at the original price
= 264 x 4
= $1056
Number of sets of 6 cricket balls
= 264 ÷ 6
= 44
Amount that it would collect if it sold the 264 cricket balls at every 6 cricket balls at $19
= 44 x 19
= $836
Amount that it would collect less from the sale of the cricket balls
= 1056 - 836
= $220
Answer(s): (a)
52175; (b) $220
