Answer:
3.3075 liters of paint
Step-by-step explanation:
7.40 (red paint) + 6.26 (blue paint ) = 13.66 (purple paint)
He pours 13.66 liters of purple paint equally into 4 containers and has 0.43 liters left.
x + x + x + x = 13.66 - 0.43
4x = 13.23
x = 13.23/4
x = 3.3075

Let be "x" the cost in dollars of a party hat and "y" the cost in dollars of a mask.
Set up a System of equations using the information given in the exercise:
You can use the Elimination Method to solve this System of equations:
1. You can multiply the first equation by -1.
2. Then you must add the equations.
3. Solve for "y".
Then:
4. Now you can substitute the value of "y" into any original equation.
5. Finally, solve for "x" in order to find its value.
Then:
