Answer: $25000
Step-by-step explanation:
From the question, we are informed that Betty made a 20% profit on a residential lot she sold for $30,000. Let the cost price of the property be represented by x.
Therefore, (100% + 20%) of x = $30000. This means that 120% of x = $30000.
120% × x = $30000
1.2x = $30000
x = $30000/1.2
x = $25000
Therefore, the amount paid for the property is $25000
