Your house had a value of $480,000 and increased in value by 3.5%. How much is your house
Phoenix [80]

Answer:

$496800

Step-by-step explanation:

You need to find 3.5% of 480,000 and then add it to 480000:

You convert 3.5% to 0.035 (divided by 100).

Now you multiply 0.035 * $480,000 = $16800 (this is the amount of money to add to the value of the house)

Total value of the house: $480,000 + $16,800 = $496800
