Suppose that the world's current oil reserves is R = 2060 billion barrels. If, on average, the total reserves is decreasing by 16 billion barrels of oil each year, answer the following: A.) Give a linear equation for the total remaining oil reserves, R, in billions of barrels, in terms of t, the number of years since now. (Be sure to use the correct variable and Preview before you submit.) R- B.) 10 years from now, the total oil reserves will be bitions of barrels. C.) If no other ol is deposited into the reserves, the world's oll reserves will be completely depleted (all used up) approximately years from now. (Round your answer to two decimal places.)

• Question 1 In 2001, a school population was 1526. By 2006 the population had grown to 1896. 1) How much did the population grow between the year 2001 and 2006? students 2) How long did it take the population to grow from 1526 students to 1896 students? years 3) What is the average population growth per year? Select an answer v 4) What was the population in the year 2000? students 5) Find an equation for the population, P, of the school t years after 2000. P. 6) Using your equation, predict the population of the school in 2015. students OQuestion 2 The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 120 minutes, the monthly cost will be $33. If the customer uses 610 minutes, the monthly cost will be $82. A) Find an equation in the form y = mr + b, where z is the number of monthly minutes used and y is the total monthly of the Ringular plan. Answer: y = B) Use your equation to find the total monthly cost if 692 minutes are used. Answer: If 692 minutes are used, the total cost will be dollars.
