Write an explict equation of how a computer at 2500$ depricates at the rate of 14% per year

V(t)  = 2500(0.86)^t  where t = the year.

Step-by-step explanation:

Each year the  value will be 100 - 14 = 86% ( - 0.86) of the previous year.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
