the cost of the dress is $80.​

Answer 1

Answer:

$560

Step by step explanation:

shoe+dress = $640

shoe= $80

therefor, dress = $640-$80 = $560

Answer 2

Step-by-step explanation:

let the dress cost =X

pair of shoes cost = 80 less than dress

=x-80

total cost = $ 640

X + X - 80 =640

2x =640+80

X =720/2

X =360

cost of dress = X = 360

cost of shoes =x-80= 360-80=280
