8% less
100-8=92
P=present amount
F=future amount=f(t)
t=time in years
rate of decay is 8% or times 92%
is the equation or
is the equation or
16 because 3 divided by 8 is 0.375 and 6 divided by 0.375 is 16.
We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144
-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
