Question 155559: Write an equation containing one variable and solve it to answer this word problem. The average number of inches of rain in New York is one inch more than three times the average rainfall in December. The combined rainfall in August and December is 9.8 inches, find the rainfall for each month. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! In August the average number of inches of rain in New York is one inch more than three times the average rainfall in December.
---------
Let the average in December be "x" inches.
Then August average number is 3x + 1
--------------------------------------------------------------
The combined rainfall in August and December is 9.8 inches,
find the rainfall for each.
EQUATION:
x + 3x+1 = 9.8 inches
4x = 8.8 inches
x = 2.2 inches (amount in December)
3x+1 = 7.6 inches (amount in August)
