Home Renovation Budget #

Planning a kitchen remodel and backyard patio. Uses averages, square roots, constants, booleans, and rate conversions.

Kitchen Remodel #

Three contractor quotes for the full kitchen:

quote_a = 8500 → 8.5K
quote_b = 9200 → 9.2K
quote_c = 7800 → 7.8K

average_quote = average of quote_a, quote_b, quote_c → 8.5K

Room Measurements #

Kitchen dimensions (in feet) and the diagonal for countertop layout:

kitchen_length = 15 → 15
kitchen_width = 12 → 12
kitchen_sqft = kitchen_length * kitchen_width → 180
diagonal = sqrt(kitchen_length ^ 2 + kitchen_width ^ 2) → 19.209373

Circular Patio #

The backyard patio is a 12-foot diameter circle:

patio_radius = 6 → 6
patio_area = PI * patio_radius ^ 2 → 113.097336

Concrete is sold per square foot. Show exact area for the order:

patio_area as precise → 113.097336

Material Costs #

Cabinets and countertops:

cabinets = $6200 → $6,200.00
countertop_sqft = 45 → 45
countertop_rate = $75 → $75.00
countertops = countertop_sqft * countertop_rate → $3,375.00

Patio concrete at $8/sqft (rounded up to nearest whole number):

patio_concrete = patio_area * $8 → $904.78

Tile flooring for the kitchen:

tile_per_sqft = $12 → $12.00
flooring = kitchen_sqft * tile_per_sqft → $2,160.00

Labor Rates #

Contractor charges $800/day. What does that cost per week?

daily_rate = $800/day → 800 $/day
weekly_rate = convert_rate(daily_rate, week) → 5.6K $/week

Material Delivery #

Lumber arrives at 2 pallets per day over the 3-week build:

total_deliveries = 2 pallets/day over 3 weeks → 42 pallets

Project Budget #

subtotal = cabinets + countertops + patio_concrete + flooring → $12.64K
contingency = 15% of subtotal → $1,895.97
total = subtotal + contingency → $14.54K

Budget Check #

The project must stay under $50,000 with at least $2,000 contingency:

budget_ok = total < $50000 and contingency > $1500 → true
under_budget = not (total > $50000) → true

Quick Summary #

total as napkin → $15K
