Answer:   nonexperimental study

Instead, this is a survey

==================================================

Explanation:

We have a survey being conducted because the researchers are asking the students the questions. It's not an experiment because the students aren't being broken up into two groups (control group vs treatment group) to see the difference between the two if any.

Compound interest . A student get a grant of $10000 a year assuming her grant is increased by 7% each year what will her grant b
Klio2033 [76]

Answer:

Her grant in four years time will be of $13108.

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

A(t) = A(0)(1+r)^t

In which A(0) is the initial value and r is the growth rate, as a decimal.

A student get a grant of $10000 a year assuming her grant is increased by 7% each year

This means that A(0) = 10000, r = 0.07

So

A(t) = A(0)(1+r)^t

A(t) = 10000(1+0.07)^t

A(t) = 10000(1.07)^t

What will her grant be in four years time?

This is A(4). So

A(t) = 10000(1.07)^t

A(4) = 10000(1.07)^4 = 13108

Her grant in four years time will be of $13108.
