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 3? Express your answer in its simplest form.
- If the shop decided to sell every 5 cricket balls at $21 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 - 85 - 80 - 75
= 60
Fraction of cricket balls left at the end of Day 3
=
60300=
15 (b)
Number of cricket balls sold from Day 4 to Day 6
= 100 + 70 + 90
= 260
Amount that it would collect if it sold the 260 cricket balls at the original price
= 260 x 5
= $1300
Number of sets of 5 cricket balls
= 260 ÷ 5
= 52
Amount that it would collect if it sold the 260 cricket balls at every 5 cricket balls at $21
= 52 x 21
= $1092
Amount that it would collect less from the sale of the cricket balls
= 1300 - 1092
= $208
Answer(s): (a)
15; (b) $208
