Answer:
Step-by-step explanation:Given that
f(x)=ax+b
so registration fee=b=$10
Each hour fee=a=$5
where x represnts hours
when
x=0
f(0)=5(0)+10
f(0)=10
f(1)=5(1)+10
f(1)=15
f(2)=5(2)+10
f(2)=20
and so on...
We know that the ocean floor has a depth of 247 ft, and we also know that the diver is<span> underwater at depth of 138 ft, so its distance from the ocean floor will be:
</span>

ft
<span>
Now, the </span>rock formations rises to a peak 171 to above the ocean floor, so to find <span>how many feet below the top of the rock formations is the diver, we are going to subtract the distance to the driver form the ocean floor from the rock formations height:
</span>

ft
<span>
We can conclude that the diver is 62 feet </span><span>
below the top of the rock formations.</span>
