Answer:
6 years
Step-by-step explanation:
Simple interest= P.R.T
I = $1300
P = 18000 deposit
Rate = 1.19%
T = ?
Putting into the formula we have
1300 = 18000x1.19/100xT
1300 = 18000x0.0119xT
1300 = 214.2T
Divide through to get T
T = 1300/214.2
= 6.069
So when we approximate T = 6 years
It would take 6 years to make $1300 in interest
Answer:
25 years
Step-by-step explanation:
To find the mean you need to find the sum of all numbers and divide by the number of terms there are.
In this case you would need to multiply the mean ages by the number of people used to find the mean:
35 * 3 = 105
23 * 12 = 276
Then add the total ages together:
105 + 276 = 381
Then divide by the number of total people in the office:
12 + 3 = 15
381/15 = 25.4
rounded to 25
