A fabric store sells cotton fabric for $12.50 per yard and silk fabric for $18.00 per yard. A customer purchased $X$ yards of cotton fabric and $Y$ yards of silk fabric, spending a total of $325.00. The situation is represented by the equation $12.50 X + 18.00 Y = 325.00$ . If the customer bought exactly $10$ yards of silk fabric, how many yards of cotton fabric did they buy?
