Is this the correct answer?

PV=-50,000+180,000/1+r+180,000/1+r squared=250,000

does r have a value?

oh yes, r=20%

To determine if the given expression is the correct answer, we need to examine whether it satisfies the given equation.

The equation is: PV = -50,000 + (180,000 / (1+r)) + (180,000 / (1+r)^2) = 250,000

To verify if this answer is correct, we can follow these steps:
1. Simplify the expression by carrying out the calculations in the brackets first, using the order of operations (PEMDAS).

First, let's consider the second term:
180,000 / (1+r) = 180,000 / (1+r)

For the third term:
180,000 / (1+r)^2 = 180,000 / (1+r)^2

2. Combine the terms within parentheses:
-50,000 + (180,000 / (1+r)) + (180,000 / (1+r)^2) = -50,000 + (180,000 / (1+r)) + (180,000 / (1+r)^2)

3. Simplify further by finding a common denominator and combining like terms if possible.

At this point, we can see that we cannot simplify the expression further because there is no clear link to the left-hand side of the equation, which is 250,000.

Therefore, the expression provided (PV = -50,000 + (180,000 / (1+r)) + (180,000 / (1+r)^2) = 250,000) is not the correct answer.
