Is it statement 1 because statement 1 looks out of place.
Answer:
10/25
10+9+6 equals 25 and there is 10 red marbles. I think this is the answer don't take my word for it.

4.</span>Multiply both numbers on the second fraction by the bottom number of the first fraction.
5.Line both fractions up side by side with their new numbers.<span>
6.</span>Add together the numerators of the two fractions.<span>
7.</span><span>Take the common denominator that you figured out in Step 2 and add it on the bottom of your new numerator.
8.</span>Put the new numerator on top and the new denominator on bottom.
9.<span>Simplify and reduce.</span>
The equation is r(x) = 10x - 0.025x² where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.
For maximum r, r'(x) = 0
It becomes: r'(x) = 
= 
x= 200
Hence, r(200) = 
Solving it we get,
r(200) = 1000
Hence, maximum revenue the company can earn with this toy is $1000.
