Answer 2

Answer:

Stacia needs 52 diamonds for 4 chandeliers and 130 diamonds for 10 chandeliers.

Step-by-step explanation:

As number of diamonds and no. of chandeliers are directly proportional.

For 4 chandeliers, let no. of diamonds=x

So, 39 : 3 : :  x : 4

     39/3 = x/4

   39 × 4= 3x

 (39 ×4 ) /3 =x

       x= 52

For no. of chandeliers , let no. of diamond is y

So, 39 : 3 : : y :10

      39/3 = y/10

    39× 10 =3y

  (39 ×10) /3 =y

    y= 130
