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

porfavor en español pls para yo poder resolverlo
Because ABCD is an isosceles trapezoid, the angles A and D are congruent.
BA and CD are congruent (given) and AD is congruent to itself (reflexive property).
Then triangles BAD and CDA form a pair of SAS triangles, so they are congruent.
BD and CA are corresponding parts in those triangles, so they are congruent (CPCTC).
