Store A sells fabric for $3.00 per yard.

Store B sells packages of fabric for $3.00 each.

The cost of fabric at either store can be modeled by the function c (t) = 3t, where t is the number of yards of fabric at Store A and t is the number of packages of fabric at Store B.

The domain of c (t) = 3t is all real numbers.

For each store, drag all the additional restrictions needed on values of t for c (t) to model each situation.

Store A:

sells fabric for $ 3.00 per yard:

c (t) = 3t

The domain restrictions for this case are:

numbers greater than or equal to zero

Equivalently:

t that belongs to [0, infinity)

Store B:

sells packages of fabric for $ 3.00 each:

c (t) = 3t

The domain restrictions for this case are:

numbers greater than or equal to zero: [0, infinity)

integer values only: (1,2,4 ... n)
