The image contains a list of Engineering Economics (EngEcon) problems that require the computation of various financial values using different formulas. Here’s a breakdown of the problems presented:

1. **Mortgage Calculation**: A house costs P1.3 Million. A buyer pays P300,000 as a down payment and will pay the remaining amount in 48 monthly installments, starting at the end of 1 year. The interest rate is 20.4% compounded monthly. The task is to find the monthly installment.

2. **Present Value of an Annuity**: Find the present value of 10 semi-annual payments of P3,000, with the first payment at the end of 3.5 years. The interest rate is 12% compounded semi-annually.

3. **Future Value of an Annuity**: P10,000 is deposited quarterly at the beginning of every 3 months for 8 years, with a 5% interest rate compounded quarterly. The task is to find the total amount in the fund at the end of 8 years.

4. **Cash Equivalent of Rent**: The monthly rent of an apartment is P15,000, payable at the beginning of each month, with money worth 15% compounded monthly. Find the cash equivalent of 5 years' rent.

5. **Present Value and Amount of an Annuity Due**: Determine the present value and amount of an annuity that pays P25,000 semi-annually for 9.5 years, with an interest rate of 7% compounded semi-annually.

6. **Present Worth of Perpetuity**: Calculate the present worth of a perpetuity that pays P6,000 annually, with an interest rate of 10% compounded monthly.

7. **Present Value of a Deferred Annuity**: Find the present value of a deferred annuity that pays P5,200 semi-annually, starting at the end of 4 years and continuing forever, with a 7.6% interest rate compounded semi-annually.
