A sports shop had 400 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 $23 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
= 400 - 95 - 90 - 85
= 130
Fraction of cricket balls left at the end of Day 3
=
130400=
1340 (b)
Number of cricket balls sold from Day 4 to Day 6
= 60 + 90 + 100
= 250
Amount that it would collect if it sold the 250 cricket balls at the original price
= 250 x 5
= $1250
Number of sets of 5 cricket balls
= 250 ÷ 5
= 50
Amount that it would collect if it sold the 250 cricket balls at every 5 cricket balls at $23
= 50 x 23
= $1150
Amount that it would collect less from the sale of the cricket balls
= 1250 - 1150
= $100
Answer(s): (a)
1340; (b) $100
