The mobile phone is bought for 10000 rupees and loses 800 rupees in value every year. After 3 years, the value decreases by 800 multiplied by 3, which equals 2400 rupees. Therefore, the remaining value becomes 10000 minus 2400, which equals 7600 rupees. If t represents the number of years and v reprRead more
The mobile phone is bought for 10000 rupees and loses 800 rupees in value every year. After 3 years, the value decreases by 800 multiplied by 3, which equals 2400 rupees. Therefore, the remaining value becomes 10000 minus 2400, which equals 7600 rupees. If t represents the number of years and v represents the value of the phone, then the expression is v = 10000 minus 800t. This represents linear decay because the decrease remains constant every year.
