A recipe for spagetti sauce requires four 16-ounce bottles of ketchup to make 2 gallons of sauce. How many bottles of ketchup are needed to make 8 gallons of spagetti sauce?
Cross multiply and solve for x.
2/4 = 8/x
To find out how many bottles of ketchup are needed to make 8 gallons of spaghetti sauce, we can use a proportion.
First, let's set up the proportion:
16 ounces of ketchup / 2 gallons of sauce = X bottles of ketchup / 8 gallons of sauce
To solve for X (the unknown number of bottles of ketchup), we cross multiply:
(16 ounces of ketchup) * (8 gallons of sauce) = (2 gallons of sauce) * (X bottles of ketchup)
This simplifies to:
128 ounces of ketchup = 2 * X bottles of ketchup
Now, we can solve for X by dividing both sides of the equation by 2:
X bottles of ketchup = 128 ounces of ketchup / 2
X bottles of ketchup = 64 bottles of ketchup
Therefore, to make 8 gallons of spaghetti sauce, you would need 64 bottles of ketchup.
