Answer:
New monthly salary: $264.96
Explanation:
you would first change your percent into a decimal.
our given percent is 8% = 0.08
then after that multiple by the original principal
288 x 0.08
this equation will give you 23.04
next you would then have to subtract the given product from by the original principal once again.
288-23.04
this equation will then give you your sum of $264.96
as his new monthly salary.
