Question 178201
<font face="Times New Roman" size="+1">

First thing to do is change the dollars and cents to cents, eliminating the decimal fractions in your variable coefficients.  It doesn't really matter in the end, it is simply neater and you are less prone to arithmetic error.


Let *[tex \large x] equal the required number of pounds of chocolate chip cookies.


The value of the chocolate chip cookies in the mix will then be *[tex \large 695x \text { cents}]


The value of the white chocolate cookies in the mix will be *[tex \large 595(4) = 2380 \text { cents}]


The value of the mix has to be *[tex \large 675(4 + x) =  \text { cents}]


But the value of the mix also has to be the sum of the values of the two ingredients, namely:


*[tex \large 2380 + 695x \text { cents}]


So set these two expressions equal to each other and solve for x.



*[tex \large 2380 + 695x = 675(4 + x)]
