To determine the amount of money Phyllis will save by buying the TV at Store B instead of Store A, we should compare the prices of the TV at both stores.
The price of the TV at Store A is $498, and the price at Store B is $425. To find the savings, we need to subtract the price at Store B from the price at Store A.
So, we calculate the difference between the two prices:
$498 (Store A's price) - $425 (Store B's price) = $73
By subtracting the price at Store B from the price at Store A, we find that Phyllis will save $73 by purchasing the TV at Store B.
