Answer by jim_thompson5910(35256) About Me  (Show Source):
You can put this solution on YOUR website!
A = kG

9.66 = k(9)

9.66/9 = k

1.07333 = k

k = 1.07333

-------------------------------------------------------

A = kG

A = 1.07333G

A = 1.07333(4)

A = 4.29332


So the 4th grader's weekly allowance is $4.29 a week
