$5.55
per pound, and type B coffee costs
$4.45
per pound. This month, Chau made
161
pounds of the blend, for a total cost of
$825.35
. How many pounds of type A coffee did he use?

He used 74.4 lbs of type A coffee. 
If he is using a mixture of two divide the total of cost by 2 to get the amount of what one of the coffee costed, then divide that by 5.55 and you get the answer.
