A sports shop had 350 cricket balls for sale. Each cricket ball is sold at $4. 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 $17 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
= 350 - 100 - 70 - 60 - 95
= 25
Fraction of cricket balls left at the end of Day 4
=
25350=
114 (b)
Number of cricket balls sold from Day 5 to Day 6
= 65 + 90
= 155
Amount that it would collect if it sold the 155 cricket balls at the original price
= 155 x 4
= $620
Number of sets of 5 cricket balls
= 155 ÷ 5
= 31
Amount that it would collect if it sold the 155 cricket balls at every 5 cricket balls at $17
= 31 x 17
= $527
Amount that it would collect less from the sale of the cricket balls
= 620 - 527
= $93
Answer(s): (a)
114; (b) $93
