A sports shop had 400 cricket balls for sale. Each cricket ball is sold at $3. 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 $14 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
= 400 - 96 - 66 - 66 - 96
= 76
Fraction of cricket balls left at the end of Day 4
=
76400=
19100 (b)
Number of cricket balls sold from Day 5 to Day 6
= 66 + 108
= 174
Amount that it would collect if it sold the 174 cricket balls at the original price
= 174 x 3
= $522
Number of sets of 6 cricket balls
= 174 ÷ 6
= 29
Amount that it would collect if it sold the 174 cricket balls at every 6 cricket balls at $14
= 29 x 14
= $406
Amount that it would collect less from the sale of the cricket balls
= 522 - 406
= $116
Answer(s): (a)
19100; (b) $116
