A sports shop had 500 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 4? Express your answer in its simplest form.
- If the shop decided to sell every 6 cricket balls at $26 from Day 5 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 4
= 500 - 114 - 66 - 60 - 72
= 188
Fraction of cricket balls left at the end of Day 4
=
188500=
47125 (b)
Number of cricket balls sold from Day 5 to Day 6
= 78 + 66
= 144
Amount that it would collect if it sold the 144 cricket balls at the original price
= 144 x 5
= $720
Number of sets of 6 cricket balls
= 144 ÷ 6
= 24
Amount that it would collect if it sold the 144 cricket balls at every 6 cricket balls at $26
= 24 x 26
= $624
Amount that it would collect less from the sale of the cricket balls
= 720 - 624
= $96
Answer(s): (a)
47125; (b) $96
