Answer:
30%
Step-by-step explanation:
It’s A because when you add the anti force to the molecular cause of the yah
<em>x</em> = amount invested at 8 %. Then 23 000 - <em>x</em> = amount invested at 9 %
Annual income (<em>I</em>) = interest at 8 % + interest at 9 %
<em>I</em> = 0.08<em>x</em> + 0.09(23 000 – <em>x</em>)
<em>I</em> = 0.08<em>x</em> + 2070 – 0.09<em>x</em>
<em>I</em> = 2070 – 0.01<em>x</em>
Only 4 because result is (x-4)(x-4) that means (x-4)^2=0
So
X-4=0
X=4
