The advertisement shows the cost of buying markers from a stationery shop.
- Emma bought 27 markers. How much did she pay?
- Asher bought 60 markers. How much did he pay?
(a)
Number of sets of 15 markers
= 27 ÷ 15
= 1 r 12
Cost of first 15 markers
= 15 x 2.50
= $37.50
Cost of the next 12 markers
= 12 x 2.10
= $25.20
Amount that Emma paid
= 37.50 + 25.20
= $62.70
(b)
Number of markers that was not part of the first 15 markers
= 60 - 15
= 45
Cost of first 15 markers = $37.50
Cost of the next 45 markers
= 45 x 2.10
= $94.50
Total cost of 60 markers before an additional discount of 6% is applied
= 37.50 + 94.50
= $132
Amount that Asher paid in percent after an additional discount of 6% is applied
= 100% - 6%
= 94%
100% of the total cost of 60 markers = 132
1% of the total cost of 60 markers = 132 ÷ 100 = 1.32
94% of the total cost of 60 markers = 94 x 1.32 = 124.08
Amount that Asher paid = $124.08
Answer(s): (a) $62.70; (b) $124.08
