Answer:
5000 ≥ 2000 + 50a
Step-by-step explanation:
She wants to save at least $5000 for college. The saving account set up by her parents already contains $2000 . This means she has more $3000 to save to meet her minimum target. Each month she saves $50 into the account.
Let
number of month = a
The information can be expressed as follows
5000 ≥ 2000 + 50a
The savings will continue increasing every months because she always deposit $50 every month.
Using the expression
5000 ≥ 2000 + 50a
minus 2000 from both sides
3000 ≥ 50a
divide both sides by 50
3000/50 ≥ a
60 ≥ a
This means she needs at least 60 months to meet her savings/target.
Step-by-step explanation:
let the total students be x then
25/100x=9
x=9×100/25
x=9×4
x=36
so total students are 36
To calculate the mean of a set of numbers and them all together and divide by the amount of numbers.
Example:
Find the mean of 12, 25, 36.
12 + 25 + 36 = 73
73 / 3 = 24.33
Our mean is 24.33.
