A sports shop had 500 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 4 cricket balls at $12 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 - 52 - 76 - 64
= 308
Fraction of cricket balls left at the end of Day 3
=
308500=
77125 (b)
Number of cricket balls sold from Day 4 to Day 6
= 44 + 60 + 68
= 172
Amount that it would collect if it sold the 172 cricket balls at the original price
= 172 x 4
= $688
Number of sets of 4 cricket balls
= 172 ÷ 4
= 43
Amount that it would collect if it sold the 172 cricket balls at every 4 cricket balls at $12
= 43 x 12
= $516
Amount that it would collect less from the sale of the cricket balls
= 688 - 516
= $172
Answer(s): (a)
77125; (b) $172
