Danny has at least $15 more than his big brother. danny's big brother has $72.how much money does danny have? write an inequality to solve each problem

If Danny has AT LEAST $15 dollars more than his brother, and his brother has $72, then the equality would start out like this (where d = the amount of money Danny has):



Because he has AT LEAST $15 more; it could be exactly 15, or it could be any number more than 15.  So, to simplify:



Danny has at least $87 ($87 or more).
