Answer:
20, 000
Step-by-step explanation:
For a duration of 50 years, the consumption will be equal to the product of annual consumption and the number of years hence 800*50=40, 000 barrels.
Since 20, 000 barrels are unknown and they are part if consumption in the next 50 years, then the known or proven reserves will be given by getting the difference between total consumption and unknown reserve, expressed as 40, 000-20, 000=20, 000 barrels.
487.2
Find mean by adding all numbers together and then dividing by the number of numbers
When you estimate you round to the nearest whole number (simply to make it easier.) Depending on what place you need to estimate to (like hundreds, or just tens..)
Let's turn 196 into 200 and 482 into 480
200+480 = 680
Hope this hlps!
