A sports shop had 300 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 $12 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 - 30 - 39 - 33
= 198
Fraction of squash balls left at the end of Day 3
=
198300=
3350 (b)
Number of squash balls sold from Day 4 to Day 6
= 51 + 48 + 51
= 150
Amount that it would collect if it sold the 150 squash balls at the original price
= 150 x 5
= $750
Number of sets of 3 squash balls
= 150 ÷ 3
= 50
Amount that it would collect if it sold the 150 squash balls at every 3 squash balls at $12
= 50 x 12
= $600
Amount that it would collect less from the sale of the squash balls
= 750 - 600
= $150
Answer(s): (a)
3350; (b) $150
