A sports shop had 300 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 $14 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
= 300 - 68 - 40 - 72
= 120
Fraction of cricket balls left at the end of Day 3
=
120300=
25 (b)
Number of cricket balls sold from Day 4 to Day 6
= 44 + 60 + 60
= 164
Amount that it would collect if it sold the 164 cricket balls at the original price
= 164 x 4
= $656
Number of sets of 4 cricket balls
= 164 ÷ 4
= 41
Amount that it would collect if it sold the 164 cricket balls at every 4 cricket balls at $14
= 41 x 14
= $574
Amount that it would collect less from the sale of the cricket balls
= 656 - 574
= $82
Answer(s): (a)
25; (b) $82
