Answer:
The ratio of the amount of flour to the amount of buttermilk=99:1
Step-by-step explanation:
Step 1: Determine quantity for each recipe
Quantity of flour=66 cups
Quantity of buttermilk=2/3 cups
Step 2: Calculate the total quantity of recipe
The expression for the total quantity is;
T=f+b
where;
T=total quantity of recipe
f=quantity of flour
b=quantity of buttermilk
In our case;
T=unknown
f=66 cups
b=2/3 cups
replacing;
T=(66)+(2/3)=66 2/3 cups
Step 3: Determine fraction of each
fraction of buttermilk=(2/3)/(66 2/3)=1/100
fraction of flour=66/(66 2/3)=99/100
Step 4: Determine ratio of flour to buttermilk
Amount of flour:amount of buttermilk
(99/100):(1/100)
The ratio of the amount of flour to the amount of buttermilk=99:1
This function would have a maximum.
Since we are subtracting by a -4 for each increase in x, we know that the numbers will continue to go down. Given this fact, we know the number will never be higher than when we started, but the number could go infinitely low. As a result we have a maximum and no minimum.
