Applying SImple Math to Everyday Life Activities

$4 each means that each member pays $4. A group pass for $160 means that everyone is covered, so no one has to pay individually.

Let x = the number of club members

Since we want pass to be cheaper than the total cost of individual tickets, we set the inequality

**160**

**< 4x**

Divide both side of the inequality by 4.

40 < x

x > 40

So in order for the pass to be cheaper than the total cost of individual tickets, at least 41 members must attend the trip.
