Answer:
d. 0.85m + 2.50
Step-by-step explanation:
In the figure attached, the complete question is shown.
We can see in the table that $2.50 is a fixed charge, that is, it is not modified by any variable. On the other hand, for each travelled mile, the cost of the travel increases $0.85 ($0.75 by mileage charge + $0.1 by city gas tax). Then, if m miles are travelled, the cost of the travel increases 0.85*m
In this question, it is given that
Curium-243 has a half-life of 28.5 days. In a sample of 5.6 grams of curium-243.
And we have to use the following formula, which is
Here t=12 days, half life, h =28.5 days . And the initial value ,A(0)=5.6 gms
So we will get
Therefore after 12 days, 4.2 gmsof curium-243 remains .
