The cost of building the house the next year would be $100,800.
Step-by-step explanation:
To calculate the cost of building the house the next year, we need to apply a 26 percent increase to the current cost. Let's start by finding 26 percent of $80,000:
26% of $80,000 = $80,000 * 0.26 = $20,800
Now, we'll add this amount to the current cost:
$80,000 + $20,800 = $100,800
Therefore, it would cost $100,800 to build the house the next year.
