Given:
Cost of protein = $10.25 per pound
Cost of spirulina = $22.45 per pound
Cost of blend = $16.35 per pound
Weight of blend = 140 pounds
To find:
The quantity of spirulina it will need to make the blend.
Solution:
Let x be the quantity of protein and y be the quantity of spirulina in the blend. Then,
...(i)
Equation (i) can be written as:
...(ii)

...(iii)
Using (ii) and (iii), we get




Divide both sides by 12.2.


Therefore, 70 pounds of the spirulina it will need to make the blend.

...Im not rlly that useful rn, sorry...!
I have a TI-84 graphing calculator that has a polynomial app solver on it, and i often use that since im not in algebra anymore. (i forgot how to do decomposition)--->
I do know you must use decomposition for this, or you can use the quadratic formula to substitute.
