Claudio a banking vice president took 17 neckties to Milto Cleaners. The rate for non silk ties is $3.25 per tie and for silk ties is $3.60 per tie. His total bill was $58.75. How many silk ties did he have dry cleaned?
Can you please show work on how to solve this?

S*3.6+ (17S)3.25=58.75
Is that correct? 
A classmate said the answer is 10 silk neckties. I need help working through the whole problem.

I will be happy to check and critique your work. I am not going to do it for you.
