Answer:

Step-by-step explanation:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

Chao bought a boat for HK$160 000
Dennis_Churaev [7]

Answer:

$141,557.76

Step-by-step explanation:

Chao bought a boat for 160,000

The value of the boat reduces by 4% every year

Therefore the value of the most at the end of three years can be calculated as follows

= 100%- 4%

= 96%

= 160,000 × 96/100^3

= 160,000 × 0.96^3

= 160,000 × 0.884736

= 141,557.76

Hence the price of the boat after 3 years is 141,557.76
