the manager of a store that specializes in selling tea decides to experiment with a new blend. she will mix some earl grey tea that sells for $5 per pund with some orange pekoe tea that sells for $3 per pound to get 100 punds of the new blend. the selling price of the new blend is to be $4.50 per pound, and there is to be no difference in revenue from selling the enw blend versus selling the other types.|||x = pounds of earl grey
y = pounds of pekoe
x + y = 100 ---%26gt; x = 100 - y
4.5 dollars a pound equals to 450 dollar for 100 pounds
5x + 3y = 450
Now, plug in the x -value obtained through the first equation, into the second equation:
5(100-y) + 3y = 450
Solve for y ---%26gt; y = 25
So we need 25 pounds of pekoe and 75 pounds of earl grey.
