Answer:
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y = k x (or y = k x ) where k is the constant of variation . Example 1: If y varies directly as x and y = 15 when x = 24 , find x when y = 25 .

Answer:
x=13 feet
Step-by-step explanation:
A ramp is between 1.96 and 1.80 feet, we will take 1.96
and R(x)=1.96 feet: we apply quadratic formula; 
, where a=-0.05, b=0.8 and c=-1.96, so
solving 
; we take the highest value of x, x=13
