200 – (74 + (720/9) + 44 + 16 x (4 + 6 – 8 x 2) - (42/2) + 70) – 2
200 – (74 + 80 + 44 + 16 x (-6) - 21 + 70) – 2
200 – (74 + 80 + 44 - 96 - 21 + 70) – 2
200 – 151 – 2

If there are equal amounts of blue and green marbles, then there are 56 of each; so 112 altogether. That leaves 28 red and yellow marbles; therefore 14 red marbles.
Answer:
No, she doesn't have enough varnish for all the floors.
Step-by-step explanation:
Area of the floor, A= 10x6-5x2=50 
Since 5 m^2 required 1 liter of varnish.
So, the amount of varnish required for 1
= 1/5= 0.2 liters.
The amount of varnish required for 50
= 0.2X50=10 liters.
Now, as 1 tin has 2.5 liters of varnish.
So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.
Hence, she doesn't have enough varnish for all the floors.
Example:a+b=b+a
ab=ba
(a+b)+c = a(b+c)
