Question 1105681
The Patronete Winery's tastiest wine must have a 12% alcohol content.
 How many gallons of wine with a 9% alcohol content must be mixed with 3,000 gallons of wine with a 15% alcohol content in order to achieve the desired 12% alcohol content?
:
let x = amt of 9% wine required
An equation using the decimal equiv of per cent
.09x + .15(3000) = .12(x+3000)
.09x + 450 = .12x + 360
450 - 360 = .12x - .09x
90 = .03x
x = 90/.03
x = 3000 gal of 9% required
