I figured it out in my head.
The unit price per padlock would be $4.40
Work: $17.60 (17.60)÷4= 4.4 ($4.40)
Answer:
147 seconds to get to the shore(after the 49 seconds)
Step-by-step explanation:
If Pete swam at a constant speed of 50 yards/49 seconds, you just have to multiply that by four, to get 200 yards. If you want the total time from his boat to shore, that is 196. If you want how much longer it would be, it would be 147 seconds
for minutes, just divide by 60
This is an exponential growth problem of the form:
F=Ir^t, F=final amount, I=initial amount, r=rate, t=time
In this case:
F=50(1.08^t)
F(17)=50(1.08^17)
F(17)=$185.00
Factor the numerator using difference of cubes:

a = x
b = 2

Now you can evaluate limit as x=2.
