0.5*x+0.6*y=0.6(200) where x is quantity of 1st and y is 2nd vinegar.
so, 5x+6y=6(200)=1200
5x+6y=1200......(1)
x+y=200..........(2)
(1)-5*(2)⇒y=1200-1000=200,x=0
so, you just take 200 ml of second vinegar. In fact, this calculation can be skipped coz we were asked the 2nd vinegar directly in the question.
Answer:
About 33,199,213
Step-by-step explanation:
Population of America: about 331,992.130 million
331,992,130 x .10 = 33,199,213
Multiplying by 0.1 is the same as dividing by 10, as 0.1 = 1/10
So, 37.4x 0.1 = 37.4/10 = 3.74
