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:
The answer to your question is letter A. Regular size is cheaper than Economy size by $0.0003 per gram
Step-by-step explanation:
Cost of 1 gr of economy size
5000 gr (5 kg) ------------------- $ 5.15
1 gr -------------------- X
x = 1 x 5.15 / 5000 = $0.0010
Cost of 1 gr of regular size
820 gr ------------------- $0.60
1 gr -------------------- x
x = 1 x 0.6 / 820 = $ 0.0007
Difference of cost = $0.0010 - $0.0007 = $0.0003
The answer would be a (not too sure) but it makes a little bit sense
