Compounded once a year: A=P(1+r)^t
2500=500(1+0.095)^t
1.095^t=5
because the unknown number is an exponent, use log to find the unknown:
log(1.095^t)=log5
tlog1.095=log5
t=log5/log1.095
use your calculator, t=17.734
so this person is about 28 years old.
        
             
        
        
        
Answer:
rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k =  =  ← ratio of lengths
k =  =  ← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k =  =  ← ratio of lengths
k =  =  ← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k =  =  ← ratio of lengths
k =  ← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
