Me! you! : )
during the months of august and september the total rainfall was 6.2 inches. if the rainfall in august was 0.6 inch more than the amount of rainfall in september, how much rain fell in each month?

All we need to do is to divide August and September rainfall measurements into two equal halves and then substract 0.6 from one of them and add 0.6 to the other one.

6.2 ÷ 2 = 3.1
3.1 - 0.6 = 2.5
3.1 + 0.6 = 3.7

It's said that in August there was 0.6 inch more rainfall, so the bigger value (3.7 inches) is for August and the smaller value (2.5 inches) is for September.

Aline graph should be used
