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

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

\(\frac{1}{3}\) of 40.95 can be calculated as follows ->

\(\frac{1}{3}\) = \(\frac{x}{40.95}\)
simplify to get that x = 27.30

30% of 40.00 can be calculated as follows ->

\(\frac{30}{100}\) = \(\frac{x}{40.00}\)
simplify to get that x = 28
