- 1.1700 — Total spending = $500 + $300 + $200 = $1000. Left over = $2700 − $1000 = $1700.
- 2.2000 — Total spending = $500 + $400 + $800 = $1700. Left over = $3700 − $1700 = $2000.
- 3.1400 — Total spending = $200 + $400 + $800 = $1400. Left over = $2800 − $1400 = $1400.
- 4.1300 — New rent = $700 + $100 = $800. Leftover = $2700 − $800 − $600 = $1300.
- 5.2050 — New rent = $1200 + $50 = $1250. Leftover = $3600 − $1250 − $300 = $2050.
- 6.1050 — New rent = $800 + $250 = $1050. Leftover = $2700 − $1050 − $600 = $1050.
- 7.15100 — Monthly leftover = $2900 − $1600 = $1300. Over 12 months: $15600. After insurance: $15600 − $500 = $15100.
- 8.22000 — Monthly leftover = $3100 − $1200 = $1900. Over 12 months: $22800. After insurance: $22800 − $800 = $22000.
- 9.11100 — Monthly leftover = $2200 − $1200 = $1000. Over 12 months: $12000. After insurance: $12000 − $900 = $11100.
