A sports shop had 300 cricket balls for sale. Each cricket ball is sold at $3. 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 4 cricket balls at $8 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
= 300 - 40 - 64 - 44 - 60
= 92
Fraction of cricket balls left at the end of Day 4
=
92300=
2375 (b)
Number of cricket balls sold from Day 5 to Day 6
= 80 + 72
= 152
Amount that it would collect if it sold the 152 cricket balls at the original price
= 152 x 3
= $456
Number of sets of 4 cricket balls
= 152 ÷ 4
= 38
Amount that it would collect if it sold the 152 cricket balls at every 4 cricket balls at $8
= 38 x 8
= $304
Amount that it would collect less from the sale of the cricket balls
= 456 - 304
= $152
Answer(s): (a)
2375; (b) $152
