Question

There are 3 in. of snow on the ground when it begins to snow 0.5 in/h .

Which linear equation represents the total depth of the snow, in inches, after x hours?



Responses

a y=0.5x+3
a y equals 0.5 x plus 3

b 3+y=0.5x
b 3 plus y equals 0.5 x

c x=0.5y
c x equals 0.5 y

d y=0.5x
d y equals 0.5 x

Answer 1

Answer: a) y = 0.5x + 3

Reason: start with 3 in of snow and add 0.5 inches per hour, so total depth y = initial 3 + rate 0.5×hours (x).
