In this question, the average general expenditure of our country's consumer on dairy products is given by the function g of x is equal to 310 .3 plus 40 .1 natural log of x, where if x is equal to 6, this implies that the expenditure is for the year 2006.
00:25
Now, for the first subpart, we need to obtain the expenditure for the year 2010, which implies that the value of x should be 10.
00:36
Substitute xs 10 in the given equation to obtain the solution.
00:41
That would be 310 .3 plus 40 .1, natural log of 10.
00:49
That is 310 .3 plus 92 .23, which give the solution as 402 .53.
01:04
Hence, the average general expenditure for the year 2010 is 402 .53.
01:12
Now, for the second subpart, we need to obtain the average general expenditure for the year 2014.
01:22
That means the next is 40.
01:24
Substitute the value of xs14 in the given equation and solve for g of 14.
01:32
310 .3 plus 40 .1 times natural log of 40, which gives the solution as 310 .3 plus 105 .864.
01:49
This gives the solution as 416 .16 .16...
