285 didn't go. bc u subtract the percent and 350
In a year there are 12 months
in 6 years there are 72 months
that means he paid a total of 72(225) = $16200
$16200 minus the original $15,000 he took out leaves us with the amount of interest he paid which is $1,200
therefore answer A is correct
Yes she is correct just do the proper calculations
