We are given
Let's assume
number of days =x
the cost in dollars of a loaf of bread in a bakery =y
we have
the cost in dollars of a loaf of bread in a bakery is equal to 2 minus 0.25 times the number of days since it was baked
so, we get
It will not make sense when cost is negative
so, we set y=0
and then we can solve for x
We add both sides by 0.25x
Divide both sides by 0.25
and we get
So, after 8 days , the cost will become negative
which does not make sense
because cost can never be negative ............Answer
