A sports shop had 450 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 6 cricket balls at $27 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
= 450 - 60 - 90 - 96 - 114
= 90
Fraction of cricket balls left at the end of Day 4
=
90450=
15 (b)
Number of cricket balls sold from Day 5 to Day 6
= 108 + 108
= 216
Amount that it would collect if it sold the 216 cricket balls at the original price
= 216 x 5
= $1080
Number of sets of 6 cricket balls
= 216 ÷ 6
= 36
Amount that it would collect if it sold the 216 cricket balls at every 6 cricket balls at $27
= 36 x 27
= $972
Amount that it would collect less from the sale of the cricket balls
= 1080 - 972
= $108
Answer(s): (a)
15; (b) $108
