Answer:

А . Marcos made an incorrect conversion from centimeters to inches. The correct price is $23.03.

Explanation:

Given that,

Length of fabric = 1.3 meters

We know that,

1 m = 100 cm

⇒1.3 m = (1.3)×100 = 130 cm

⇒1.3 m = 130 cm

Now,

We know that

1 inch = 2.54 cm

and

1 cm = 0.3937 inches

⇒130 cm = (130)×(0.3937) inches

= 51.181 inches

⇒130 cm = 51.181 inches

Now,

Given that,

Cost of 1 inch = $0.45

⇒Cost of 51.181 inches = $(51.181)×(0.45)

= $ 23.03

∴ we get

The cost of fabric = $23.03

and

The correct option is - А . Marcos made an incorrect conversion from centimeters to inches. The correct price is $23.03.
