Given:
Principal = $1290
Rate of simple interest = 4%
Time = 9 months
To find:
The interest and total saving in the account altogether.
Solution:
The formula for simple interest is
...(i)
where, P is principal, r is rate of interest and t is time in years.
We know that,
Putting P=1290, r=4 and t=0.75 in (i), we get
So, the simple interest is $38.70.
Total savings is
Therefore, the total amount in the account altogether is $1328.70.
1. 5.25 + 8.95 = 14.20
2. 21.32 - 9.50 = 11.82
3. 24.50 × 5 = 122.5
4. 85.20 ÷ 4 = 21.3
Hope this helped! Please comment if you have any questions regarding how I got my answers. Stay safe.
