Percentage Raise in salary for the new year = 5%
The new yearly salary can be obtained thus ;
(100% + percentage raise in salary) * salary earned this year
(100% + 5%) * 23,000
105% * 23000
1.05 * 23000
24,150
the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
To convert to a decimal, divide by 100.
75 / 100 = .75
X=# of weeks passed
150+2X=195-X
3X=45
X=15
