Respuesta :

Nina spent $80

EXPLANATION

Given:

Cost per foot = $6

Nina bought four fence and each measuring 3 ft 4 inch.

3 ft 4 inch

• We need to first convert to ft.

1 ft = 12 inch

⇒ 1 inch = 1/12 ft = 0.33333

3ft 4 inch = 3.33333 feet

• Since Nina bought four of the fence, then ;

4 x 3.333333 = 13.3333333 feet

1 ft = $6

13.3333333 feet = 13.3333333 x 6 = $79.99999999998 ≈ $80

Hence, Nina will spend $80
