A sports shop had 300 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 4? Express your answer in its simplest form.
- If the shop decided to sell every 4 cricket balls at $6 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
= 300 - 56 - 40 - 72 - 56
= 76
Fraction of cricket balls left at the end of Day 4
=
76300=
1975 (b)
Number of cricket balls sold from Day 5 to Day 6
= 52 + 52
= 104
Amount that it would collect if it sold the 104 cricket balls at the original price
= 104 x 2
= $208
Number of sets of 4 cricket balls
= 104 ÷ 4
= 26
Amount that it would collect if it sold the 104 cricket balls at every 4 cricket balls at $6
= 26 x 6
= $156
Amount that it would collect less from the sale of the cricket balls
= 208 - 156
= $52
Answer(s): (a)
1975; (b) $52
