Explanation / Answer

25) let tea A = x pounds

tea B = y pounds

setting up the equations

x + y = 10

4x + 2.75y = 10* 3.50

multiplying equation 1 by -4

-4x - 4y = -40

adding equation 2 to it

-4x - 4y = -40

4x + 2.75 y = 35

-----------------------

y = 4

x = 6

so, 6 pounds of tea A and 4 pounds of tea B should be mixed
