LED (light-emitting diode) bulbs are rapidly decreasing in cost, and they are more energy-efficient than standard incandescent light bulbs and CFL (compact fluorescent light) bulbs. Haitz's law predicts that the cost per lumen LED bulb decreases by a factor of 10 every 10 years. This means that 10 years from now, the cost of an LED bulb will be 1/10 of its current cost. Predict the cost of a particular LED bulb in 2023 if it costs 4 dollars in 2018. Create an exponential model for the given situation. Use the exact value for k in the function. y(t) =D (Type an expression using t as the variable.)
