A sports shop had 350 cricket balls for sale. Each cricket ball is sold at $2. 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 5 cricket balls at $7 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
= 350 - 60 - 75 - 90
= 125
Fraction of cricket balls left at the end of Day 3
=
125350=
514 (b)
Number of cricket balls sold from Day 4 to Day 6
= 95 + 95 + 70
= 260
Amount that it would collect if it sold the 260 cricket balls at the original price
= 260 x 2
= $520
Number of sets of 5 cricket balls
= 260 ÷ 5
= 52
Amount that it would collect if it sold the 260 cricket balls at every 5 cricket balls at $7
= 52 x 7
= $364
Amount that it would collect less from the sale of the cricket balls
= 520 - 364
= $156
Answer(s): (a)
514; (b) $156
