Answer: 25 + d
Step-by-step explanation:
Since there are 30 drummers competing in the Battle of the Bands this year and, 5 of the drummers will leave the following year, the number of drummers left will be gotten by the expression:
= 30 - 5
If If d is the number of drummers who will then join the competition, therefore, the expression that represent the number of drummers in the competition next year will be gotten as:
= 30 - 5 + d
= 25 + d
Therefore, the expression is 25+d.
