Given:
The given table represents the ingredient need to make 4 muffins.
To find:
The amount of flour needed to make 12 muffins.
Solution:
We have, the data for 4 muffins.
From the given table it is clear that,
Flour need for 4 muffins = 250 g
Flour need for 1 muffins = g
Flour need for 12 muffins = g
= g
= g
So, 750 g flour is need to make 12 muffins.
Therefore, the correct option is D.
Using an exponential function, it is found that it takes 18.6 days for 80% of the material to decay.
The amount of a substance after t days is modeled by:
In which:
- k is the decay rate, as a decimal.
- A(0) is the initial amount.
The half-life is of 8 days, hence , and this is used to find k.
Hence:
The time it takes for 80% of the material to decay it t for which , hence:
It takes 18.6 days for 80% of the material to decay.
