Answer:
d >= $87
Explanation:
Since we are not given the exact difference between the amount of money that Danny has in comparison to his brother, then this would ultimately be an inequality question. We are told that Danny has atleast $15 more than his brother, meaning that the minimum that Danny can have is $15 more than his brother. Danny's brother has $72 so we need to add these two values together.
$72 + $15 = $87
Therefore Danny would have a minimum of $87 but at the same time can have more than that. Therefore, we can use the following inequality to represent Danny's money (d)
d >= $87
