Question 957227: A weather balloon is filled with hydrogen at the rate of 0.5 ft^3/s. Initially, the balloon contains 2ft^3 of hydrogen.
a) Find a linear function V that models the volume of hydrogen in the balloon at any time t.
b) If the balloon has a capacity of 15ft^3, how long does it take to completely fill the balloon.

(a)
+V+=+.5t+%2B+2+
(b)
+V+=+15+
+15+=+.5t+%2B+2+
+.5t+=+13+
+t+=+26+
It takes 26 sec to completely fill the balloon
