Question

Below, you are given the 2012 value of a product and the rate at which the value is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the year. (Let t = 12 represent 2012.) 2012 Value Rate $48,000 $2200 decrease per year

Answer 1

`y = 48000 - 2200x` --- equation

`y = 37000` --- value at 5th year

Explanation:

Given

`Value = \$48000`

`Rate = \$2200` decrease

Required

Determine the linear equation

Determine the value at the 5th year

Represent years with x.

If the rate in 1 year is 2200,

in x years, it'll be 2200x (decrement)

So, the value (y) at x years is.

`y = 48000 - 2200x`

The value at the 5th year is when x = 5.

So, we have:

`y = 48000 - 2200 * 5`

`y = 48000 - 11000`

`y = 37000`
