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 4 cricket balls at $12 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 - 48 - 52 - 68 - 60
= 122
Fraction of cricket balls left at the end of Day 4
=
122350=
61175 (b)
Number of cricket balls sold from Day 5 to Day 6
= 44 + 52
= 96
Amount that it would collect if it sold the 96 cricket balls at the original price
= 96 x 4
= $384
Number of sets of 4 cricket balls
= 96 ÷ 4
= 24
Amount that it would collect if it sold the 96 cricket balls at every 4 cricket balls at $12
= 24 x 12
= $288
Amount that it would collect less from the sale of the cricket balls
= 384 - 288
= $96
Answer(s): (a)
61175; (b) $96
