You get 1/4 a pint for 1 dollar. Because each pint is 4$,
A + b = 147....a = 147 - b
5.85a + 4.40b = 786
5.85(147 - b) + 4.40b = 786
859.95 - 5.85b + 4.40b = 786
-5.85b + 4.40b = 786 - 859.95
- 1.45b = -73.95
b = -73.95 / -1.45
b = 51 <== she used 51 lbs of type B coffee
It would still be 11.5% no matter how you put or state it
