Mango mixed 24 ounces of blue paint with 16 ounces of red paint to create a new purple color. In order to create 72 more ounces of this exact purple color, how many ounces of red paint would she need

Respuesta :

Parrain

Answer: 28.8 ounces of red paint

Step-by-step explanation:

The total amount of paint created the first time Mango mixed colors was:

= 24 + 16

= 40 ounces of purple color

For 40 ounces of purple, 16 ounces of red was needed. Proportion is therefore:

= 16/40

If one wants 72 ounces of purple therefore:

= Proportion of red used * 72 ounces

= 16/40 * 72

= 28.8 ounces of red paint
