Question

At the end of a snowstorm, Ellie had 16 inches of snow on her lawn. The temperature then increased and the snow began to melt at a constant rate of 1 inch per hour. Assuming no more snow was falling, how much snow would Ellie have on her lawn 4 hours after the snow began to melt? How much snow would Ellie have on her lawn after tt hours of snow melting?

Answer 1

12 inches

Explanation:

1 x 4 = 4

16 - 4 = 12

Answer 2

Snow after 4 hours: 16 Show after t hours: -1t

Explanation:

Snow after 4 hours:

starting amount = 16

melted snow= inches per hour×4

=1×4

=

4

final amount= starting amount−melted snow

= 16−4

=12

​

Snow after t hours:

starting amount= 16

melted snow= inches per hour×t

=1×t

=1t

final amount= starting amount−melted snow =16-1t
