Answer:
8 lb of flounder at $2.50/lb
4 lb of shrimp at $5.00/lb
Step-by-step explanation:
Let A be the pounds of shrimp
Let B be the pounds of flounder
Let C be the cost per pound of flounder
A + B = 12
A = 12 - B
BC = 20
A(2C) = 20
BC = A(2C)
BC = (12 - B)(2C)
BC = 24C - 2BC
3BC = 24C
3B = 24
B = 8 lb
A + 8 = 12
A = 4 lb
8(4)-5(1)+2(4)
Multiply
32-5+8
Solve from left to right
28+8
36
The answer is 36
Answer:
