Correct option is:
a. 7 years
Step-by-step explanation:
Aaron's mother purchases a new computer for $1750.
she claims loss of value on the computer at a rate of $250 per year
i.e. After t years value of computer= $ (1750-250t)
How long will it take for the value of the computer to be $0?
i.e. We have to find the value of t such that:
1750-250t=0
⇒ 250t=1750
⇒ t=1750/250
⇒ t=7
Hence, correct option is:
a. 7 years
