From the graph of the linear functions, we have that both snowman's will have the same height of 21 inches after 5 hours.
A linear function is modeled by:
y = mx + b
In which:
For this problem, we have that:
Hence the functions are given as follows:
The functions are graphed at the end of the answer, with A(t) in red and B(t) in blue, and they intersect at (5,21), meaning that both snowman's will have the same height of 21 inches after 5 hours.
