D) 
Step-by-step explanation:
All number of years equal the amount when plugged in
If it is perimeter add 15+15 and 5+5 and if it is area then just do 15 times 5 and if it is perimeter 15 plus 15 is 30 and 5 plus 5 is 10 so 30 plus 10 is 40 and if you are doing 15 times 5 is 75 depends if it is perimeter or area
8 is a whole number, so this will be the whole number part of our mixed number.
0.25 is a decimal, where 25 is in the HUNDREDths place, so we write 25 as a fraction over 100.

Simplify by dividing 25 to the numerator and denominator.


So our fraction is

0.55 is a decimal, where 55 is in the HUNDREDths place, so we write 55 as a fraction over 100.

Simplify by dividing 5 to the numerator and denominator.


So our fraction is


To convert this to a decimal, just divide 5 / 8
