Answer: $350+$85w greater than or equal to $715

Explanation:

$350 = already saved up money
$85w = additional money each week (we don’t know how many weeks we need to save up in order to reach our goal, so the number of weeks is unknown)

The sign is greater than or less than because you either have to reach the exact total of $715 or more than that.

Now, solve.

$350+$85w greater than or equal to $715
$85w greater than or less than $365
w greater than or less than 4
