Answer:

Step-by-step explanation:
Given
Yearly Cost for members; 
Required
Determine the yearly cost for non members
From the question, we understand that:
<em>A non member pays $0.20 for each game;</em>
Yearly cost is then calculated as thus;
y = Amount * Number of Games
Where:
Amount = $0.2 and Number of Games = x

Convert 0.2 to fraction

Divide the numerator and the denominator by 2


<em>Hence, the yearly cost for non members is </em>

$15 * .06= tax
or $15(.06)= tax
just multiply the price by the decimal form of the sales tax to get the tax amount.
