The maturity stage of the product life cycle is the longest stage, where sales peak and profit margins narrow. in this stage, new users or new uses may be added to extend the product life.
Introduction, growth, maturity, and decline are the four stages that make up a product's life cycle. Professionals in management and marketing use product life cycles to assist them to decide on advertising schedules, price points, expanding into new product markets, redesigning packaging, and more.
When sales reach their maturity stage, they start to slow down after a period of strong expansion. At this stage, businesses start lowering their prices in an effort to remain competitive against the escalating competition. The product life cycle's mature stage lasts the longest. At this time, the company has reached the peak of the demand cycle, sales growth is starting to slow down, and advertising tactics aren't doing anything to help.

Answer:
a. How long will the current bridge system work before a new bracing system is required?: 64.18 years or 64 years and 2 months.
b. What if the annual traffic rate increases at 8 % annually: The bracing system will last for 24.65 years or 24 years and 7 months.
c. At what traffic increase rate will the current system last only 12 years: 17.13%
Explanation:
a. Denote x is the time taken for the number of pedestrian to grow from 300 to 2000. The current pedestrian is 300, the grow rate per year is 3% or 1.03 times a year. Thus, to reach 2,000, we have the equation: 300 x 1.03^x = 2000. Show the equate, we have 1.03^x = 6.67 <=> x = 64.18
b. Denote x is the time taken for the number of pedestrian to grow from 300 to 2000. The current pedestrian is 300, the grow rate per year is 8% or 1.08 times a year. Thus, to reach 2,000, we have the equation: 300 x 1.08^x = 2000. Show the equate, we have 1.08^x = 6.67 <=> x = 24.65.
c. Denote x as traffic increase rate. The current pedestrian is 300, the grow rate per year is (1+x) times a year. Thus, to reach 2,000 after 12 years and thus a new bracing system to be in place, we have the equation: 300 x (1+x)^12 = 2000. Show the equate, we have (1+x)^12 = 6.67 <=> 1+x = 1.1713 <=> x = 17.13%.
