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 zeronumbers greater than or equal to zeronumbers less than zerointeger values onlynumbers less than 3numbers greater than 3
Question
Answer:
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)
