Answer:
The statement is not reasonable.
Step-by-step explanation:
Josefina gave away 130% of her stamp collection.
We cannot give more than what we have.
lets understand it mathematically.
suppose i have x stamp.
according to question, i have to give 130% of my stamp collection
130% of x = 130/100 x = 1.3x
so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.
maximum i can give is x stamp.
x stamp in percentage of my total stamp collection which is also x will be
= x/x*100 = 100%
Thus, maximum one can give is 100% of what he has.
Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The given equation is

Javier has to solve for n
He can multiply through by 100 to get;

He can now divide through by 775 to obtain:

He can now easily simplify to get:

We rewrite as a power to get:

 
        
             
        
        
        
Answer: 
c<5, and  c>-4.
<u>Steps used for answers:</u>
5c+3<28 = 
1. Subtract 3 from both sides.
5c<28-3
2. Simplify  28-3 to  25.
5c<25
3. Divide both sides by 5.
c<25/5
4. Simplify  25/5 to 5.
c<5
-----------------------
-4c-2<14 = 
1. Add 2 to both sides.
-4c<14+2
2. Simplify  14+2 to 16.
-4c<16
3. Divide both sides by -4.
c>-16/4
4. Simplify 16/4 to 4.
c>−4
