Domain considering the scenario: Justin has $10 in his account and plans to save $25 each week until he reaches $135 for the new game he wants to buy.
Domain: The number of weeks Justin plans to save.
and how many weeks is that
To determine the number of weeks Justin needs to save, we can use the equation:
$10 + $25x = $135
Simplifying the equation, we have:
$25x = $125
x = 5
Therefore, Justin needs to save for 5 weeks to reach a total of $135 in his account.
The domain for this scenario would be the set of positive integers less than or equal to 5, since Justin cannot save for fractions or negative weeks. So, the domain would be {1, 2, 3, 4, 5}.
