A sports shop had 400 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 3? Express your answer in its simplest form.
- If the shop decided to sell every 6 cricket balls at $28 from Day 4 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 3
= 400 - 78 - 66 - 60
= 196
Fraction of cricket balls left at the end of Day 3
=
196400=
49100 (b)
Number of cricket balls sold from Day 4 to Day 6
= 78 + 84 + 84
= 246
Amount that it would collect if it sold the 246 cricket balls at the original price
= 246 x 5
= $1230
Number of sets of 6 cricket balls
= 246 ÷ 6
= 41
Amount that it would collect if it sold the 246 cricket balls at every 6 cricket balls at $28
= 41 x 28
= $1148
Amount that it would collect less from the sale of the cricket balls
= 1230 - 1148
= $82
Answer(s): (a)
49100; (b) $82
