He puts 1/4 of the treasure to aside for himself he gives 1/2 of what is left to his friend bill he shares 2/3 of the remaining
Andrej [43]

Answer:

24 bars of treasure

Step-by-step explanation:

You just need to do the opposite in order to find the total value since you divided the treasure up we need to multiply the treasure “back”.

3 buried bars is equal to 1/3 of the remaining treasure. Multiply by 3 to get 3/3 or 100% of buried and crew portion. So we now have 9 bars. Then multiply by 2 to get 100% of what was given to bill, crew and buried. We now have 18 bars. Then we know that we took 1/4 for ourselves so that means 18 bars represents 3/4 of the treasure. So when we look at factors of 18 we find that 3 x 6 = 18 and 4 x 6 = 24 so we conclude that we had 24 bars of treasure before the split.

The common factor of given terms is x/8, which is given in option B.

<h3>What is factor?</h3>

A factor is a number that divides another number, leaving no remainder.

Here, given terms are:

 \frac{5}{8}x     and      \frac{11}{8} x

Now, factors of 5x/8 = 5 X 1/8 X (x)

        factors of 11x/8 = 11 X 1/8 X (x)

So, common factors are 1/8 and x

Thus, the common factor of given terms is x/8, which is given in option B.

C. what is the implied tax (i.<br> e., tax/average income) on the highest quintile?
maria [59]
 <span>The answer is derived from the top quintile LOSS of 101,800 which is due to taxes in other words this is the taxes paid. Therefore, the taxes paid divided by the average income of 170,000 or shown as 101,800/170,000 = .5988 which rounds to .60 or 60% implied tax rate. </span>
