Answer 1

`at\ Alan's\ sports\ shop:\\\£40.95- (1)/(3) \cdot\£40.95= (2)/(3) \cdot\£40.95=\£27.30\\ \\At\ Irene's\ sport\ shop:\\\£40.00-30\%\cdot \£40.00=70\%\cdot \£40.00=0.70\cdot \£40.00=\£28.00\\ \\Ans.\ Less\ cost\ is\ at\ Alan's\ sports\ shop.`

Answer 2

the trainers will be cheaper at Alan's sport shop.

prices ->
Alan's: 27.30
Irene's: 28.00


`(1)/(3)` of 40.95 can be calculated as follows ->


`(1)/(3)` =
`(x)/(40.95)`
simplify to get that x = 27.30

30% of 40.00 can be calculated as follows ->


`(30)/(100)` =
`(x)/(40.00)`
simplify to get that x = 28
