If a school district paid a total of $35 per desk for ~$x$~ desks and a total of $30 per table for ~$y$~ tables, what was the total amount that the district paid for these desks and tables?

1. The total amount the district paid for the ~$y$~ tables was $900.

2. ~$x$~ = 90, and the total amount the district paid for the x desks was 3.5 times the total amount the district paid for the ~$y$~ tables.
