We must find time by using the simple interest formula:
I = P x i x t
I is the interest
P is the total principal
i is the rate of interest per year
t is the total time in years
In this example, when we plug our known values in, our formula looks like this:
t =
t =
t = 4
So time (in years) would be 4 years.
I = P x i x t
I is the interest
P is the total principal
i is the rate of interest per year
t is the total time in years
In this example, when we plug our known values in, our formula looks like this:
t =
t =
t = 4
So time (in years) would be 4 years.

Harry can first substitute 30 for t. He can then multiply by 30 to get a product of 10. Since 15 is equal to 30 × 1/2, Harry's solution is not correct.
Hope this helps :)
Have a great day!
