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.

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
