A sports shop had 300 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 4? Express your answer in its simplest form.
- If the shop decided to sell every 5 cricket balls at $6 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 - 55 - 65 - 50 - 55
= 75
Fraction of cricket balls left at the end of Day 4
=
75300=
14 (b)
Number of cricket balls sold from Day 5 to Day 6
= 70 + 100
= 170
Amount that it would collect if it sold the 170 cricket balls at the original price
= 170 x 2
= $340
Number of sets of 5 cricket balls
= 170 ÷ 5
= 34
Amount that it would collect if it sold the 170 cricket balls at every 5 cricket balls at $6
= 34 x 6
= $204
Amount that it would collect less from the sale of the cricket balls
= 340 - 204
= $136
Answer(s): (a)
14; (b) $136
