Answer:

1050

Step-by-step explanation:

Let x = full capacity

\frac{3}{5} x=\frac{2}{7} x+330

Move the variable to the left side by subtracting both sides by \frac{2}{7} x

\frac{3}{5} x-\frac{2}{7}x=\frac{2}{7} x+330 -\frac{2}{7}x

\frac{3}{5} x-\frac{2}{7} x=330

Combine the like terms (don't forget about common denominator)

\frac{21}{35} x-\frac{10}{35} x=330

\frac{11}{35} x=330

Multiply both sides by \frac{35}{11} to isolate the x

(\frac{35}{11})\frac{11}{35} x=330(\frac{35}{11})

x = 1050
