Mr. Bergstrom has two water storage tanks near his vegetable garden. One morning, tank A contained 2 gallons more than 4 times the number of gallons of water in tank B. At that time, tank A had a total of 46 gallons of water.
Select the equation that represents the given situation and find the number of gallons of water in tank B.
A.
2x + 4 = 46; 11 gallons
B.
2x + 4 = 46; 21 gallons
C.
4x + 2 = 46; 11 gallons
D.
4x + 2 = 46; 21 gallons
The correct equation is:
4x + 2 = 46
Solving for x:
4x = 44
x = 11
Therefore, the number of gallons of water in tank B is 11 gallons. The correct option is C.
