Step-by-step explanation:
2 x 10¹⁴ = 200 000 000 000 000 while
4 x 10⁶ = 4 000 000
so 200 000 000 000 000 000 / 4 000 000 = 50 000 000
that means the value of 2 x 10¹⁴ is 5 x 10⁷ times the value of 4 x 10⁶

Answer:
24 munchkins.
Step-by-step explanation:
Let C be the number of chocolate and D be number of glazed donut holes in the original box.
We are told if Jacob ate 2 chocolate munchkins, then 1/11 of the remaining Munchkins would be chocolate. We can represent this information as:

We are also told if he instead added 4 glazed Munchkins to the original box, 1/7 of the Munchkins would be chocolate. We can represent this information as:
Upon substituting C's value from equation (2) in equation (1) we will get,
Let us have a common denominator on right side of equation.


Multiplying both sides of our equation by 7, we will get,

Multiplying both sides of our equation by 11, we will get,
Therefore, the total number of Munchkins in original box is 24.
The answer is 1.12% decrease
