A sports shop had 300 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 3 cricket balls at $13 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 - 30 - 30 - 36 - 36
= 168
Fraction of cricket balls left at the end of Day 4
=
168300=
1425 (b)
Number of cricket balls sold from Day 5 to Day 6
= 39 + 33
= 72
Amount that it would collect if it sold the 72 cricket balls at the original price
= 72 x 5
= $360
Number of sets of 3 cricket balls
= 72 ÷ 3
= 24
Amount that it would collect if it sold the 72 cricket balls at every 3 cricket balls at $13
= 24 x 13
= $312
Amount that it would collect less from the sale of the cricket balls
= 360 - 312
= $48
Answer(s): (a)
1425; (b) $48
