The price of product X was going for $100 per item in the year 2005, and $70 per item in the year 2015. Assume the price is changing linearly each year, and determine an expression P (t) for the price per item where t is the years since 2000. What would you expect the price to be in the year 2030?

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
