Hi,
A grocer wants to <u>make a 10-pound mixture of cashews and peanuts</u> that he can sell for $3.29 per pound. 
 If cashews cost $5.60 per pound and peanuts cost $2.30 per pound, how many pounds of each must he mix?
Let {{{highlight_green(n)}}} represent the number of pounds of cashews
 and {{{highlight_green(10-n)}}}the number of pounds of peanuts
Question states***
 $5.6n + $2.3(10-n) = $3.59/lb*(10lb) ***
 5.6n + 23 - 2.3n = 32.9
 3.3n = 9.9
 n = 3, the number of pounds of cashews
and 10-n = 7, the number of pounds of peanuts
CHECKING our answer***
 $16.80 + $16.10 = $32.90
