You need to evaluate the average cost per one day for one day pass, such that:
`$37/1 = $37`
Hence, evaluating the one-day pass average cost, under the given conditions, yields `$37.`
We have A one-day ticket to Sea World cost $37, but a two-day pass costs $42.
We wish to find is the average cost per day fo a one-day pass .Since having pass valid for two days,so one can visit Sea World 2 days by paying $42.
Average cast per day for pass = Total cost /total no. of days validity
Thus average cost per day for pass= $21.
One day ticket cost $ 37 ,it is not average cost.
