In terms of units:
( number of students ) x ( pay / hour ) x ( hours / week ) = assistants pay / week
+30%2A20%2A8.5+=+5100+
+20%2A20%2A10+=+4000+
The assistance are paid +5100+%2B+4000+=+9100+ per week
--------------
( number of months ) x ( weeks / month ) = +9%2A4+=+36+
Yearly cost = +36%2A9100+=+327600+ $327,600
