To make 3 litres of pale purple paint you mix: 1.5 litres red
1.25 litres of blue
0.25 litres of white paint.
a How much red paint is needed to make 8 litres of paint?

We need 4 litres of red paint.

Step-by-step explanation:

We need to take their respective precentages to compare the 3 litres of paint to 8 litres of paint.

Now, we know that the pale purple paint contains 50% red paint, 41.67% blue paint, and 8.33% white paint.

Now, we will transfer these percentages to the 8 litres of paint:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
