A sports shop had 300 squash balls for sale. Each squash ball is sold at $2. 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 6 squash balls at $9 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
= 300 - 96 - 72 - 60
= 72
Fraction of squash balls left at the end of Day 3
=
72300=
625 (b)
Number of squash balls sold from Day 4 to Day 6
= 90 + 90 + 102
= 282
Amount that it would collect if it sold the 282 squash balls at the original price
= 282 x 2
= $564
Number of sets of 6 squash balls
= 282 ÷ 6
= 47
Amount that it would collect if it sold the 282 squash balls at every 6 squash balls at $9
= 47 x 9
= $423
Amount that it would collect less from the sale of the squash balls
= 564 - 423
= $141
Answer(s): (a)
625; (b) $141
