Answer:

I = a/300

A = (300I + a)/300

Step-by-step explanation:

David earns 4% for the money he has in savings. Let the amount that he has initially be a. This means that his principal is a. So

P = a

The rate at which he is earning interest on the principal is 4%. Therefore,

R = 4℅

We want to calculate the amount of money in his account after one month. This means that time,

t = 1/12 (12months make a year)

The amount of money in his account after one month will be the interest earned in one month + the initial amount in the account.

To determine the interest, we will apply the simple interest formula,

I = PRT/100

Where I = interest

P = principal

T = time

The first equation will be

I = (a × 4 × 1)/12 × 100

I = 4a/1200 = a/300

The second equation will be

Amount in the account after one month,A

A = I + a/300

A = (300I + a)/300

Describe transformation given by (x,y) (x, y + 2)
Nadusha1986 [10]

Answer:

This graph has been translated. Translation is when the image on the graph has been shifted along one or both of the axis. In this case, the graph has been shifted up two units as shown by the operation of addition on the y-value. Remember that translations are rigid movements, so the new image will be congruent to the pre-image.
