Answer:
The total rainfall last year is 12.75 inches.
Step-by-step explanation:
The total rainfall this year is 10.2 inches.
Let the total rainfall last year be x inches.
It is given that the total rain this year 20% less than last year's total rainfall.
[tex]x-\frac{20}{100}x=10.2[/tex]
[tex]\frac{100x-20x}{100}=10.2[/tex]
[tex]\frac{80x}{100}=10.2[/tex]
[tex]\frac{8x}{10}=10.2[/tex]
[tex]8x=102[/tex]
[tex]x=12.75[/tex]
Therefore total rainfall last year is 12.75 inches.
