Answer 1

Answer:

Option B - $550(1+0.1)^6$

Step-by-step explanation:

Given : Fidel has a rare coin worth $550. Each decade, the coin's value increases by 10%.

To find : Which expression gives the coin's value, 6 decades from now?

Solution :

The given situation represents the exponential function,

$y=a(1+r)^n$

where, a is the initial value i.e. a=$550

r is the increased rate r=10%

n is the time i.e. n=6

Substitute the value in the formula,

$y=550(1+10\%)^6$

$y=550(1+0.1)^6$

Therefore, option B is correct.
