c) 2x+1
Step-by-step explanation:
Let's x be number of Nick's goals.
Emma has scored 1 more than twice the number of Nicks.
1 more is +1, of twices the number is 2x.
so 2x+1=15
We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).
79-74 = 5. So the mean has increased by 5 points. (C)
