Step-by-step explanation:
(a)
← divide numerator and denominator by 4
= 
= 0.8
(b)
→ divide numerator and denominator by 5
= 
= 0.7
(c)
← divide numerator and denominator by 4
= 
= 1.5

Find 
Express 32 as an exponent
By comparison:
So:
This problem is fairly simple if you know the exponential equation, you start with y=78(.17)^x. the you put 10=78(.17)^x, then you solve for x
10=78(.17)^x
-78
-68=.17^x
divide .17 then you have your answer!!
