Question

Wines at $ 4.50 and

$5 per litres are mixed
with a third wine in
the ration 2:3:4.If the mixture Cost $5.20 a litre, what is
the Cost of the third wine?​

Answer 1

The third wine costs $5.70 per litre

Explanation:

so we've got 2 parts $4.50 wine, 3 parts $5 wine and 4 parts x wine. The result is $5.20 per part.

2l*$4.50/l + 3l*$5/l + 4l*x = (2l+3l+4l)*$5.20/l

$9 + $15 + 4l*x = $46.80

4l*x = $22.80

x = $5.70/l
