A sports shop had 300 squash balls for sale. Each squash ball is sold at $4. 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 4? Express your answer in its simplest form.
- If the shop decided to sell every 4 squash balls at $14 from Day 5 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 4
= 300 - 44 - 60 - 64 - 64
= 68
Fraction of squash balls left at the end of Day 4
=
68300=
1775 (b)
Number of squash balls sold from Day 5 to Day 6
= 80 + 44
= 124
Amount that it would collect if it sold the 124 squash balls at the original price
= 124 x 4
= $496
Number of sets of 4 squash balls
= 124 ÷ 4
= 31
Amount that it would collect if it sold the 124 squash balls at every 4 squash balls at $14
= 31 x 14
= $434
Amount that it would collect less from the sale of the squash balls
= 496 - 434
= $62
Answer(s): (a)
1775; (b) $62
