Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form: ....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function:
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3
Given parameters:
Principal = £1300
Interest rate = 5%
Duration = 2yrs
Unknown:
Total amount of Dan's principal = ?
To solve this problem, we apply the equation below:
Total investment worth = Principal + interest
Interest =
where P is the principal
R is the rate
T is the time
Now, input the parameters;
Total investment worth = £1300 + £
= £1300 + £130
= £1430
The amount after two years is £1430
