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.



numbers greater than zero

numbers greater than or equal to zero

numbers less than zero

integer values only

numbers less than 3
numbers greater than 3

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)
