zzz [600]
So his job has a starting salary of $78,000 and he gets a 4% increase each year. 4% of 78,000 is 3120 since 3120 divided by .04 equals 78,000, and 78,000+3120 = 81120 x 7= 567,840. So every year he can make $81120 and multiply that by 7, Mica would earn $567,840 every 7 years with the 4% increase in his salary every year.
