Answer:
15x+25 ; 70
Step-by-step explanation:
Given that,
Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.
Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :
y = 15x+25
For 3 hours,
y = 15(3)+25
= 45 + 25
= 70
So, the required option is (c) " 15x+25 ; 70 ".

Answer:
D. The base is a positive number greater than 1
Step-by-step explanation:
The formula for exponential growth and decay is
y =a b^x
where a is the initial value
b = 1 + the growth (or decay rate)
b will be greater than 1 if we have growth and between 0 and 1 if we are decaying
