a
Step-by-step explanation:
Well in the first you buy 5P+2B+3L
but then you buy 3P +1B+2L
and you add then up
120 people who all need 1 drink, so if each drink needs .5 cups of concentrate you will do 120d × 0.5 = 60 total cups of concentrate. if you then set up a fraction, you could cross multiply to get the answer, but I cant do fractions here so I'll say this: if every 5 cups of concentrate gives 19 cups of water, then you divide 60 cups by 5 cups to see how many "batches" of this recipie you will need, you get 12 batches, so 12 x 19 (cups of water per batch) to get 218 ( I think, check my math with a calculator
we know that A has 60% of salt, so if way we had "x" amount of ounces of A solution the amount in it will be 60% of "x", or namely (60/100)*x = 0.6x.
Likewise for solution B if we had "y" ounces of it, the amount of salt in it will be (75/100) * y or 0.75y, thus
Answer: C. y=1/3x+3
Step-by-step explanation:
The line hits the y axis at 3 so 3 is the y intercept and the line rises one accross 3 so 1/3 is your slope. Together its y=1/3x+3
