Answer: the number of team members this year is 36
Explanation:
The 7th grade football team had 30 players last year. This year, there are 20% more players on the team than the previous year. This means that the number of players in the team this this year increased by an amount. The number by which the number of players increased would
20/100 × 30 = 6.
Therefore, the number of football team members in the 7th grade football team this year would be
30 + 6 = 36
