C++ if platinum or gold level customers make a late payment, then their interest rate for the month doubles. for example, if a platinum member is late, then his interest rate increases from 1% to 2% for the month. if a silver level customer is late on a payment, their interest rate does not increase. instead, they are assessed a flat $20 penalty for being late. for this assignment, you will write a program that calculates the minimum payment, which is 2% of the principle plus any interest and fees. you will also need to calculate the percentage of the payment that goes to the principle

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.
