Ivanna's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Ivanna $5.55 per pound, and type B coffee costs $4.25 per pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $556.0 . How many pounds of type A coffee were used?
Answer provided by our tutors
let
a = lbs of the type A coffee used
b = lbs of the type B coffee used
this month's blend used twice as many pounds of type B coffee as type A
b = 2a
the total cost of the blend is $556.0
5.55*a + 4.25*b = 556
by solving the system of equations
b = 2a
5.55*a + 4.25*b = 556
we find
a = 39.57 lbs
