ANSWER: E. $15.75
Solve this algebraically. Solve for x (amount fifth person gets paid).
x= [((4*12)+x) / 5] + 3
5x = 48 + x + 15
5x = 63 + x
4x = 63
x = 15.75
The 5th friend makes $15.75. This can be confirmed by adding up all 5 people’s pay and finding the average: (12+12+12+12+15.75)/5 = 12.75
$15.75 is $3 higher than the average of $12.75
