Answer:
175 ft
Step-by-step explanation:
Let c represent the change in altitude. Then an equation can be written:
150 +c = 325
We solve for c by subtracting 150 from both sides of the equation:
c = 325 -150 = 175
The change in altitude is an increase of 175 feet.
_____
This confirms the general rule that to find the value of a change, you subtract the original value from the new value. Here, that means ...
c = 325 -150 = 175 . . . . as above.
