Andrea works at a zoo that just purchased a new lion and two parakeets. andrea needs to change a section of the lion's habitat from sand to grass. she also needs to fill up the parakeets' food dispenser. her boss told her that the length of the grassy area for the lion must be 3 feet greater than its width and that the food dispenser for the parakeets must be filled up completely. to give the lion enough grass, the area of the grass must be at least 8 times greater than the radius of the parakeets' food dispenser.
the food dispenser for the parakeets is cylindrical in shape and 4 feet tall. it is exactly half-way full. the cost of the parakeets' food is $0.49 times the length of the radius for every foot of height of food missing from the dispenser. also, the landscaping crew said they could put the grass in the lion's habitat for $2.84 per square foot of grass. andrea cannot spend more than $751.00 on both projects.
if x represents the width of the grassy area and y represents the radius of the parakeets' food dispenser, then which of the following systems of inequalities can be used to determine the length and width of the grassy area and the radius of the food dispenser?
