A sports shop had 350 squash balls for sale. Each squash ball is sold at $3. 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 5 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
= 350 - 90 - 65 - 55
= 140
Fraction of squash balls left at the end of Day 3
=
140350=
25 (b)
Number of squash balls sold from Day 4 to Day 6
= 80 + 75 + 55
= 210
Amount that it would collect if it sold the 210 squash balls at the original price
= 210 x 3
= $630
Number of sets of 5 squash balls
= 210 ÷ 5
= 42
Amount that it would collect if it sold the 210 squash balls at every 5 squash balls at $12
= 42 x 12
= $504
Amount that it would collect less from the sale of the squash balls
= 630 - 504
= $126
Answer(s): (a)
25; (b) $126
