300:1. A meter is 100 cm, so 9 meters is 900 cm / 3 = 300.
Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %
Calculate x:

, which is around 90.2%.
The percent of decrease is 100 - 90.2 = 9.8 %.
A. A Plus Plumbing company charges $60 per hour and $80 as a one-time fee cause 320-140/4-1 equals 180/3 equals 60 and y-140=60(x-1)
y=60x-60+140
y=60x+80
The only point in the solution space is that of selection ...
