<PRE><B>Question 246606</B>
a baker mixes cookies worth $.95 per pound with cookies worth $1.75 per pound.how many of each kind must be used to produce a 45 pound mixture that sells for $1.25 per pound

Let x be the number of pounds of .95/lb cookies.
Then 45-x is the number of pounds of 1.75/lb cookies.

So:

45*(1.25) = .95*x +  1.25*(45-x)

Solve for x and then substitute for x to calculate 45-x.
