Matt bought an iPod from the Apple Store for $350. If it's value will depreciate by $52 a year, how much should Matt sell his iPod for in 3 years?

Respuesta :

Decreasing by $52 every year, we need to subtract 52 for each year. 

350 is the original price. 
52x is the amount decreased by how many years

350 - 52(3) = ?
350-156 = 194

Answer: Matt should sell his iPod for $194 in 3 years
Leader
The equation is
y = 350 - 52(x) where x signifies the number of years and y signifies the value of the iPod.

Since the question asks for the value after 3 years, x becomes 3.

The equation is
y = 350 - 52(3)

y = 52(3) = 156

The equation is simplified to
y = 350 - 156
y = 194

Answer: $194
