Question

if I need a pink shade of paint which consists of red and white paint. i need 128 gallons of this pink paint. the amount of red is three times the amount of white. how many gallons of each paint do i need?

Answer 1

Let the amount of white paint be = x
then, amount of red paint is = 3x
so. 3x + x = 128
4x = 128
x = 128/4 = 32
amount of red paint needed = 3*32 = 96 gallons
amount of white paint needed = 32 gallons
