Write an exponential equation for each coin that will give the coins value, v,at any time, t use the formula? coin a worth $25 and increase by 7% each year and coin b worth $40 increase by 5% each year

For coin A,

For coin B,

Step-by-step explanation:

The exponential equation is,

Where, a is the initial value,

b is the growth or decay factor,

Since, Coin A worth $25 and increase by 7% each year,

So, the coin A's value after t years,

Which is the required equation for coin A.

Now, Coin B worth $40  increase by 5% each year,

So, the coin B's value after t years,

Which is the required equation for coin B.
