A sports shop had 350 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 3? Express your answer in its simplest form.
- If the shop decided to sell every 5 squash balls at $16 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 - 100 - 100 - 75
= 75
Fraction of squash balls left at the end of Day 3
=
75350=
314 (b)
Number of squash balls sold from Day 4 to Day 6
= 75 + 85 + 70
= 230
Amount that it would collect if it sold the 230 squash balls at the original price
= 230 x 4
= $920
Number of sets of 5 squash balls
= 230 ÷ 5
= 46
Amount that it would collect if it sold the 230 squash balls at every 5 squash balls at $16
= 46 x 16
= $736
Amount that it would collect less from the sale of the squash balls
= 920 - 736
= $184
Answer(s): (a)
314; (b) $184
