a COMPLICATED ALGEBRA QUESTION

Question

Mervin tells Aquilla that he has a bag with very small rocks in it. She asks how many, and he says that if you add one hundred million very small rocks to the bag, it will contain 36 more very small rocks than the number in ten thousand of the bags minus five times the number in the bag. How many very small rocks are in Mervin’s bag?

Answer 1

x = number in bag

 

x + 100,000,000 = 36 + 10,000x - 5x

 

Solve for x.

 

100,000,000 - 36 = (10,000 - 5 - 1)x

 

99,999,964 = 9,994x

 

x = 99,999,964 / 9,994 = 10,006
