u are welcome

Answer 4

write a system of equations
4.5x+8.5y=240
x+y=40
I have this system of equations because x kg of the 4.50 bird seed and y kg of 8.50 bird seed makes 240 dollars (40*6)
also x kg + y kg equals 40 kg.
Solving the system you need 25 kg of the 4.5 peso bird feed and 15 kg of the 8.5 peso bird feed
