No, it is not because of the day of the week. Many children are less likely to go to the water park on a weekday because they have to go to school. It would be a better sampling method to go over the weekend and take a survey, so that it simulates the summer, where children have more personal time.

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs ​$70. A season ski pass costs ​$300. The
MatroZZZ [7]

The number of days when the season pass would be less expensive than the daily pass is 5 days.

<h3>How many days would the season pass be less expensive?</h3>

The equation that represents the total cost of skiing with the daily pass : (daily pass x number of days) + (cost of renting skis x number of days)

$70d + $20d = $90d

The equation that represents the total cost of skiing with the seasonal pass : cost of season pass + (cost of renting skis x number of days)

$300 + $20d

When the season pass becomes less expensive, the inequality equation is:

Daily pass > season pass

$90d > $300 + $20d

In order to determine the value of d, take the following steps:

Combine and add similar terms: $90d - $20d > $300

70d > $300

Divide both sides by 70 d > $300 / 70

d > 4.3 days

Approximately 5 days.
