Answer key · Build and modify a budget to determine a balance
- 1.2100 — Total spending = $700 + $700 + $300 = $1700. Left over = $3800 − $1700 = $2100.
- 2.2200 — Total spending = $200 + $200 + $400 = $800. Left over = $3000 − $800 = $2200.
- 3.1700 — Total spending = $400 + $600 + $800 = $1800. Left over = $3500 − $1800 = $1700.
- 4.1100 — New rent = $1200 + $100 = $1300. Leftover = $2900 − $1300 − $500 = $1100.
- 5.2400 — New rent = $900 + $100 = $1000. Leftover = $3800 − $1000 − $400 = $2400.
- 6.1750 — New rent = $800 + $250 = $1050. Leftover = $3100 − $1050 − $300 = $1750.
- 7.24900 — Monthly leftover = $3400 − $1300 = $2100. Over 12 months: $25200. After insurance: $25200 − $300 = $24900.
- 8.32900 — Monthly leftover = $3900 − $1100 = $2800. Over 12 months: $33600. After insurance: $33600 − $700 = $32900.
- 9.17100 — Monthly leftover = $2800 − $1300 = $1500. Over 12 months: $18000. After insurance: $18000 − $900 = $17100.
