Answer:
The first increase was of 60%.
Step-by-step explanation:
The initial value of the product is x.
The first increase was of y.
The second increase is of 25%, that is, 1.25.
The final price was double the original, so 2x.
This situation can be modeled by the following equation:

We want to find y.
Simplifying by x



After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.
 
        
             
        
        
        
Answer:
x2 =  -0.600000
x3 = -0.521600
Step-by-step explanation:
Given the formula;
xn+1 = (xn)³-5/10 
x2 = (x1)³-5/10 
Given x1 = -1
x2 = (-1)³-5/10 
x2 = (-1-5)/10
x2 = -6/10
x2 = -0.600000
x3 = (x3)³-5/10 
Given x3 = -0.6
x3 = (-0.6)³-5/10 
x3 = (-0.216-5)/10
x3 = -5.216/10
x3 = -0.521600
 
        
             
        
        
        
Alright, let's solve this problem! :)
<u>First we need to subtract 5k from both sides.</u>
3k−5k>12
<u>Then we simplify 3k - 5k to -2k.</u>
-2k > 12
<u>Now we divide both sides by -2.</u>
k < -12/2
<u>Now we simplify 12/2 to 6.  </u>
k < -6 
✔️Done!
Have an amazing day!
