Answer:
$300
Step-by-step explanation:
The formula for Exponential growth function =
y = a( 1 + r)^t
Where
a= Initial value = $105
y = New value after t years
r = Growth rate = 10% = 0.1
t = Time in years = 11 years
y = $105( 1 + 0.1)¹¹
y = $105(1.1)¹¹
y = $299.57725414
Approximately, = $300
Therefore, the value of the coin in 11 years is $300
