How do i enter this as a formula into excel IF function?

In cell C15, enter a formula using an IF function to determine if you need a loan. Your available cash is located on the Data sheet in cell A3 ($9000). If the price of the car is less than or equal to your available cash, display "no". If the price of the car is more than your available, cash, display "yes". Use absolute references where appropriate—you will be copying this formula across the row. The available cash is 9000

What would I enter into the Logical_test section?

5.a fishing rod is formed from a composite material of 0.5 kg of glass fibers embedded in a matrix of 0.5 kg of epoxy resin. the glass fibers are assumed to be long, continuous and unidirectional. to achieve a greater stiffness it is proposed to use a different composite that is comprised of long continuous carbon fibers that will be embedded in a matrix of 0.5 kg of epoxy resin. if the modulus of elasticity of the carbon fiber composite is 10% greater than the elastic modulus of the glass fiber composite, estimate the mass of carbon fibers that will be used to make the carbon fiber composite. assume the applied tensile stress is parallel to the direction of the long axis of the fibers. the epoxy resin, glass fiber, and carbon fiber have an elastic modulus of 5, 86, and 350 gpa respectively and a density of 1100, 2500, and 1800 respectively.
