Answer: 38,000 gallons
Step-by-step explanation:
Given : A bakery determines that producing 300 cakes requires 57 gallons of milk.
Ratio of milk to cakes = [tex]\dfrac{57}{300}[/tex] (1)
Let x be the number of gallons of milk will be required to make 200,000 cakes.
Ratio of milk to cakes = [tex]\dfrac{x}{200000}[/tex] (2)
If the gallons of milk required varies directly with the amount of cakes produced,then from (1) and (2)
[tex]\dfrac{x}{200000}=\dfrac{57}{300}\\\\ x=\dfrac{57\times200000}{300}=38000[/tex]
Hence, 38,000 gallons of milk will be required to make 200,000 cakes annually.
