a) $710
b) $640
c) $400
d) $320

Answer 1

A phone that originally sold for $800 and loses 3/5 of its value each year is worth $320 after one year, which is option d).

Step-by-step explanation:

The student has asked how much a phone originally sold for $800 is worth after one year, given that it loses 3/5 of its value each year after it is released. To find the decreased value of the phone after one year, you calculate 3/5 of the original price and then subtract that amount from the original price.

First, find 3/5 of $800:

• 3/5 * $800 = 0.6 * $800 = $480

Now, subtract the lost value from the original price:

• $800 - $480 = $320

Therefore, the phone is worth $320 after one year, which corresponds to option d).
