So the total cost depends on the price of the item(s) (c depends on p)
The independent variable is p, the price of the item, because it is not going to depend on anything else.
The dependent variable is c, because the total cost depends on how many items there are, whether your name is marked on it, etc.
The equation would be :
c = p + $3.99

Answer:
The rate of evaporation in gallons per year will be gallons per year.
Step-by-step explanation:
The amount of annual evaporation from the Hoovers dam is approximately acre-feet.
Now, 1 acre-foot of water is equivalent to 326000 gallons of water.
So, the total volume of water that evaporates per year from the dam will be
.
Therefore, the rate of evaporation in gallons per year will be gallons per year. (Answer)
