Best ResponseYou've already chosen the best response.4Since the starting amount is \($12.50\), the amount in her piggy bank in \(\text{week 0}\) is \($12.50\)

Best ResponseYou've already chosen the best response.4Can you guess the amount in her piggy bank during \(\text{week 1}\) ?

Best ResponseYou've already chosen the best response.4Yes! because she takes out \(1.25\) : \[\large 12.50\color{red}{1.25} = 11.25\]

Best ResponseYou've already chosen the best response.4Correct! you must have worked it by subtracting \(1.25\) again : \[\large 12.50\color{red}{1.25} \color{red}{1.25} = 10\]

Best ResponseYou've already chosen the best response.4Notice the pattern ? can you find the amount in her piggy bank during \(\text{week} 8\) ?

Best ResponseYou've already chosen the best response.4you just need to subtract \(\color{red}{1.25}\) for \(8\) times right

Best ResponseYou've already chosen the best response.4so the amount in the bank after \(w\) weeks is given by : \[C ~~=~~12.50~~\color{red}{1.25}w\]

Best ResponseYou've already chosen the best response.0Those are my choices C = 1.25w – 12.50 C = 1.25w + 12.50 C = –1.25w + 12.50 C = –1.25w – 12.50

Best ResponseYou've already chosen the best response.0I thought that it was C=12.501.25w but thats not up there.

Best ResponseYou've already chosen the best response.4Yes \[C ~~=~~12.50~~\color{red}{1.25}w\] is same as \[C ~~=~~\color{red}{1.25}w~+~12.50\]
