The ratio of savings to expenditure is 2:8 find the savings if the expenditure is 24,000

the savings is 6000

Step-by-step explanation:

We are told that the ratio of savings to expenditure is 2: 8, that is, that person saves 2 when he spends 8.

They tell us to find the savings when the cost is 24,000, so we are left with:

24000 * 2/8 = 6000

which means that when 24000 are spent the savings is 6000

 which agrees with the last answer option you listed

Step-by-step explanation:

Notice that you can factor by grouping, extracting a factor from the first two terms shown:

Not addressing the last two terms, you can extract a common factor "7" then obtaining:

So, notice that the full expression is simply:

which contains a common factor (x-4) that can be finally extracted to obtain the

Since neither multiplicative binomial can be factored out further (they are both prime binomials), then the factorization of the initial polynomial is:
