The function f(x)=2.5x models the amount of water, in quarts, in a bucket after x seconds. Sally needs to fill a 55- quart bucket. Which is the most appropriate domain for the function ?

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
