<PRE><B>Question 1065533</B>
The coffee Jim likes is composed of 98.5% water and 1.5% cocoa.
 The coffee John likes is composed of 97% water and 3% cocoa.
How many ounces of water, x, should be added to 20 ounces of coffee that John likes to make the coffee that Jim likes?
:
write an equation in terms of percent cocoa
.03(20) = .015(x+20)
.6 = .015x + .3
.6 - .3 = .015x
.3 = .015x
x = .3/.015
x = 20 oz of water added
:
:
The original AMT of cocoa is unchanged
.03(20) = .6 oz is the original amt of cocoa
Check the percent
.6/20 = .03 Johns
.6/40 = .015 Jims
