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 4? Express your answer in its simplest form.
- If the shop decided to sell every 4 squash balls at $4 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 - 64 - 80 - 44 - 72
= 40
Fraction of squash balls left at the end of Day 4
=
40300=
215 (b)
Number of squash balls sold from Day 5 to Day 6
= 80 + 76
= 156
Amount that it would collect if it sold the 156 squash balls at the original price
= 156 x 2
= $312
Number of sets of 4 squash balls
= 156 ÷ 4
= 39
Amount that it would collect if it sold the 156 squash balls at every 4 squash balls at $4
= 39 x 4
= $156
Amount that it would collect less from the sale of the squash balls
= 312 - 156
= $156
Answer(s): (a)
215; (b) $156
