What can you think of that has significantly increased in price during your lifetime?

Phones, Gas, and Fresh Food

Explanation:

I think the increase in the prices of these things is thanks to:

Phones: More advanced technology, but it's harder to obtain the materials needed

Gas: Foreign oil is becoming more expensive as other countries capitalize the industry

Fresh Food: Food that is produced in factories is cheaper, and less and less people are farmers. Also, farming is difficult, and producing good crops for millions of people is difficult.

1) the stages a new product goes through from beginning to end, i.e., the stages that a product passes through from introduction through growth, maturity, and decline. 2) the time from initial research and development to the time at which sales and support of the product to customers are withdrawn. 3) the period of time during which a product can be produced and marketed profitably.
