A sports shop had 450 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 $12 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
= 450 - 56 - 68 - 56 - 76
= 194
Fraction of squash balls left at the end of Day 4
=
194450=
97225 (b)
Number of squash balls sold from Day 5 to Day 6
= 76 + 48
= 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 $12
= 31 x 12
= $372
Amount that it would collect less from the sale of the squash balls
= 496 - 372
= $124
Answer(s): (a)
97225; (b) $124
