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.

Question

Select the equation that represents the given situation and find the number of gallons of water in tank B.
A.
2x + 4 = 46; 21 gallons
B.
4x + 2 = 46; 21 gallons
C.
2x + 4 = 46; 11 gallons
D.
4x + 2 = 46; 11 gallons

Answer 1

The correct equation is 4x + 2 = 46.

Subtract 2 from both sides:
4x = 44
Divide by 4:
x = 11

Therefore, the number of gallons of water in tank B is 11 gallons.

So, the answer is option D: 4x + 2 = 46; 11 gallons
