Same kind of twopart mixture problem, just different numbers

A, amount of type A coffee
144-A, amount of type B coffee
4.2A%2B5.95%28144-A%29=697.55 for accounting cost
-
4.2A%2B5.95%2A144-5.95A=697.55
%284.2-5.95%29A=697.55-5.95%2A144

A=%28697.55-5.95%2A144%29%2F%284.2-5.95%29---------compute this, pounds.
