First find the cost of the case: $1000 * 20% = $<<1000*20*.01=200>>200

Then find the cost of the headphones: $200 / 2 = $<<200/2=100>>100

Then find how much the phone contract will cost over a year: $200/month * 12 months/year = $<<200*12=2400>>2400

Finally, add the cost of the phone, accessories, and plan over the first year to find the total: $2400 + $100 + $200 + $1000 = $<<2400+100+200+1000=3700>>3700
