Question 1179986
Same kind of twopart mixture problem, just different numbers


A, amount of type A coffee
144-A, amount of type B coffee

{{{4.2A+5.95(144-A)=697.55}}} for accounting cost

-

{{{4.2A+5.95*144-5.95A=697.55}}}

{{{(4.2-5.95)A=697.55-5.95*144}}}


{{{A=(697.55-5.95*144)/(4.2-5.95)}}}---------compute this, pounds.
