A sports shop had 500 cricket balls for sale. Each cricket ball is sold at $2. 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 $6 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 - 60 - 50 - 95
= 295
Fraction of cricket balls left at the end of Day 3
=
295500=
59100 (b)
Number of cricket balls sold from Day 4 to Day 6
= 75 + 55 + 95
= 225
Amount that it would collect if it sold the 225 cricket balls at the original price
= 225 x 2
= $450
Number of sets of 5 cricket balls
= 225 ÷ 5
= 45
Amount that it would collect if it sold the 225 cricket balls at every 5 cricket balls at $6
= 45 x 6
= $270
Amount that it would collect less from the sale of the cricket balls
= 450 - 270
= $180
Answer(s): (a)
59100; (b) $180
