Question

At the beginning of a snowstorm, Ashley had 7 inches of snow on her lawn. The snow then began to fall at a constant rate of 3 inches per hour. Assuming no snow was melting, how much snow would Ashley have on her lawn 3 hours after the snow began to fall? How much snow would Ashley have on her lawn after t hours of snow falling?

Answer 1

Looks to me like
y = 7+3x

Answer 2

1) after 3 hours of snow, she would 16 inches of snow. [ 7+3(3)=16 ]

2) 3t+17
