For the second one it is about $100.
To find the amount of money for the credits, do 15×182×2, and you get $5460.
For the technology fee and the books, multiply both by 2, so 320×2=640 and 107×2=214.
Add all those together and you get $6314. For the 5 years do 5×12 months and you get 60, then do $6314/60 and you get about $100.
