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.
Has to be correct. I did it on paper and checked it. Then I checked it with a calculator
Answer:
x1 = 1 x2= 1/2
Step-by-step explanation:
DELTA= b^2-4*a*c
DELTA=(-6)^2-4*4*2= 4 >0 ==> 2 solutions
x1 = (-b+sqrtDELTA)/2*a = (6+2)/2*4 = 1
x2 = (-b-sqrtDELTA)/2*a = (6-2)/2*4 = 1/2
Use a calculator it’s easier and will give u an instant answer
