Red and white paint are mixed to make pink paint. If the amount of red paint needed is half the amount of white paint, how many
Lady_Fox [76]

Answer:

We will need about 3.3 gallons of red paint.

Step-by-step explanation:

Let

  • r = amount of red paint
  • w = amount of white paint

The amount of red paint is half the amount of white paint.

r = 1/2 w

w = 2r [1]

We need to make a total of 10 gallons. Then,

r + w = 10 [2]

Replacing [1] in [2]

r + (2r) = 10

3r = 10

r = 3.3

We will need about 3.3 gallons of red paint.
