Aking decided to share his collection of precious rubies with his three daughters. he gave his oldest
daughter, clara, 20% of the rubies. he gave harriet, his middle daughter, 25% of those that were left. he
gave his youngest daughter, melissa, 30% of the remaining rubies. after each daughter had received her
share, the king saw that there were 21 rubies left in his collection,
fet 75%
how many rubies did the king have in his collection to begin with?
how many did each daughter receive?

Suppose king has 100% of rubies and he decided to give 20% away so he's left with 80%. After that he decided to give 25% of 80% so he's left with 60% of the total rubies. Moreover he distributed 30% of the 60% he had finally he has only 42% of the original left with him that totalled to 21

42x/100=21

x=50

King had total 50 rubies

First daughter share= 50*20%= 10

Second daughter share= 40*25%= 10

Third daughter share= 30*30% = 9

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
