Prompt

Each

3.0

-ounce serving of cheddar cheese and each

1.2

-ounce serving of tuna provides about

1

microgram of vitamin B12. If a total of

3.0

micrograms of vitamin B12 are consumed from eating

x

ounces of cheese and

y

ounces of tuna, which equation best represents this situation?

0.83 x + 0.33 y = 3.0

3.0 x + 1.2 y = 3.0

1.2 x + 3.0 y = 3.0

0.33 x + 0.83 y = 3.0
