Answer 1

blusa : $121.5

short: 7.5 %

calcetines: $80.45

botas: 60.9%

sueter: $190

blusa:

135=100%

=10%

135 × 10 = 1350

1350 ÷ 100 = 13.5

135 - 13.5 = 121.5

short:

$200 = 100%

$150 =

150 × 100 = 1500

1500 ÷ 200 = 7.5

calcetines:

$85 = 100%

= 5%

85 × 5 = 455

455 ÷ 100 = 4.55

85 - 4.55 = 80.45

botas:

650 = 100%

390 =

390 × 100 = 39000

39000 ÷ 640 = 60.9

suéter

= 50%

380 × 50 = 19000

19000 ÷ 100 = 190
