A sports shop had 500 squash balls for sale. Each squash ball is sold at $5. At the end of each day, the number of squash balls sold was recorded in the bar graph shown.
- What fraction of the total number of squash balls was left at the end of Day 3? Express your answer in its simplest form.
- If the shop decided to sell every 3 squash balls at $13 from Day 4 onwards, how much less would it collect from the sale of the squash balls?
(a)
Number of squash balls left at the end of Day 3
= 500 - 45 - 30 - 45
= 380
Fraction of squash balls left at the end of Day 3
=
380500=
1925 (b)
Number of squash balls sold from Day 4 to Day 6
= 36 + 60 + 51
= 147
Amount that it would collect if it sold the 147 squash balls at the original price
= 147 x 5
= $735
Number of sets of 3 squash balls
= 147 ÷ 3
= 49
Amount that it would collect if it sold the 147 squash balls at every 3 squash balls at $13
= 49 x 13
= $637
Amount that it would collect less from the sale of the squash balls
= 735 - 637
= $98
Answer(s): (a)
1925; (b) $98
