Since he’s already at -15, if he writes a check for 7 then he’s subtracting more from his account.

I think that date has been changed...but it used to be the deadline to file ur taxes
Step-by-step explanation:
mean score means the sum of all 6 scores divided by the number of games : 6.
sum6/6 = 15
sum6 = 15×6 = 90
(sum6 + x)/7 = 16
sum6 + x = 16×7 = 112
90 + x = 112
x = 22
they scored 22 points in the 7th game.
7.6, 8.2, 8.8, 9.4, 10.0, 10.6, 11.2, 11.8, 12.4
