Therefore, Option 1 is correct.
Step-by-step explanation:
We have been given the quadratic equation:
If we compare it will general quadratic equation which is:
Here, a=5,b=3 and c= -4.
Now, we will use the formula:
And then
Where,
Therefore, Option 1 is correct.
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
