Answer:
V = $3.50t + $90.5....
Step-by-step explanation:
V(t) is a function of t that expresses the value in year 2000+t.
We know that the increase is $3.50 times t.
So,
V(t) = $3.50t + c
where c is the constant.
V(15) = $3.50 (15) + c = $143 [t=15 as mentioned in the question]
and therefore
c = $143 - $3.50 (15)
c= $143 - $52.50
c= $90.5
Now we got the value of c. We can write the equation as
V = $3.50t + $90.5....
Answer:
You could talk on the phone for 200 minutes at night, or 40 minutes during the day.
For every 5 minutes you reduced your night time talking, you could talk during the day for 1 minute.
Step-by-step explanation:
0.50d + 0.10n < $20
0.50d < $20 --> d < 40 minutes
0.10n < $20 --> n < 200 minutes
