the original value of an investment is $1,800. if the value has increased by 7% each year, write an exponential to model the situation. then, find the value of the investment after 15 years

• carlosego: For this case we have an equation of the form:
   y = A (b) ^ t
   Where,
   A: initial amount
   b: growth rate
   t: time
   Substituting values we have:
   y = 1800 * (1.07) ^ t
   For 15 years we have:
   y = 1800 * (1.07) ^ 15
   y = 4966.256773 $
   Answer:
   An exponential to model of the situation is:
   y = 1800 * (1.07) ^ t
   the value of the investment after 15 years is:
   y = 4966.256773 $
