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)
      ...(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.

Subtract the $60 out of the total first
250 - 60 = 190
Divide this value by pay per sale:
190 / 4.50 = 42.2222
Thus, they must make 43 sales in order to meet the goal
