Okay, so for this question, they want us to come up with an equation to figure out how many coins jane deposits after the nth day.
00:09
And it tells us on the first of the month that jane deposits 11 coins.
00:14
Right.
00:14
So i'm going to say that y equals 11, because that's how many she deposits on the first day, plus seven times n.
00:26
N, that represents the day number, minus one.
00:31
Now, why did i do the minus one here? the minus one is going to help us kind of take off that first day, right? on the first day, she puts 11 plus, you know, i need one minus one to be zero, so that cancels out there.
00:45
Now, if we want to kind of simplify this by multiplying it out, we could have y equals 11 plus 7n minus seven...
