Answer:
10 minutes
Step-by-step explanation:
Let's call the Acme Company A and Beltone as B
Let m be the number of minutes
A = $21 + $0.05m
B = $15 + $0.11m
- A = B
- $21 + $0.05m = $15 + $0.11m
- $6 + $0.05m = $0.11m
- $6 = $0.06m
- 10 = m
It will take 10 minutes for both prices to be equal.

To find the number of half lives divide the total number of days by the number of days for 1 half live:
1104 / 138 = 8
There are 8 half lives.
To find the total amount left multiply the starting amount by 1/2 to the 8th power:
38 * 0.5^8 = 0.148 = 0.15 grams
The answer is the last one.
