how much does he still owe after 3 years? (8) A car costs \( \$ 64000 \). Ir depreciates by \( 25 \% \) in the first year, by \( 20 \% \) in the second year, and by \( 15 \% \) in each of the following years. Find the value of the car to the nearest \( \$ 50 \) after 4 years. (9) A person saves \( \mathrm{z} \ddagger 30000 \) at \( 4 \frac{1}{2} \% \) compound interest. She adds 000 to her amount at the end of each year. Find her total savings after 2 years. (10) A man borrows 185000 at \( 6 \% \) compound interest. He pays back \( \not \not \pm 45000 \) at the end of each year. How much does he still owe after he has made his second repayment?

After the first year, the car’s value drops to \( \$ 48,000 \) (after 25%). By the end of the second year, it further depreciates to \( \$ 38,400 \) (20% off \( \$ 48,000 \)). In the third year, depreciation reduces it to approximately \( \$ 32,640 \) (15% off \( \$ 38,400 \)). Finally, after the fourth year, it’s estimated at \( \$ 27,744 \), rounding to \( \$ 27,750 \) for a neat final value. In the second scenario, after 2 years of saving with \( 4.5\% \) interest and annual contributions of \$1,000, the person will have approximately \( \$ 34,968 \). This includes the interest earned and the yearly contributions added, making those savings grow rather nicely!
