Question

a water tank is filled with 100 gallons of water. the tank loses 2 gallons of water per day from evaporation. write an equation that represents the situation

Answer 1

Answer:

y=100-2x

Step-by-step explanation:

Lets say that y is the total water in gallons and x is the number of days passed.

There will need to be 100 total when x is 0.

There will also need to be two gallons lost for every day passed represented as 2x.

This means that the gallons in the tank is 100-2x.

y=100-2x

Hope this helps.
