At a grocery store, apples cost $2 per pound and oranges cost $3.50 per pound. The function representing the total cost, in dollars, for x pounds of apples and x pounds of oranges is f(x) = 5.5x. How does the mathematical domain of the function compare to the reasonable domain?
Answers: 1
consists of multypling the input by a factor of 5.5. This operation can be done with any type of number, so the domain of the function is the set of real numbers. However, in the context of the problem, it doesn't make sense to have negative values of x,since x represents a weight of apples and oranges. Then, in the context of the problem 
. So the reasonable domain of the function is the set of real numbers that are greater or equal to zero. In this case, the reasonable domain is proper subset of the mathematical domain, since they are obviously not equal (hence it is a proper subset).

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
