Question

Ryan's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Ryan
$4.05
per pound, and type B coffee costs
$5.50
per pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of
$511.70
. How many pounds of type A coffee were used?

Answer 1

Gibran,

 

Assume x lbs of type A was used, type B = 2x lbs

 

4.05x + 5.5(2x) = 511.70

 

x = 34

 

34 lbs of type A was used

Answer 2

Let x = pounds of A

 

 

4.05x + 5.50(2x) = 511.70

 

 

Solve for x

Answer 3

thirty-four is correct!      (same equation)
