andera deposited 300$ in savings account that pays 3% simple annual interest, How much interest will andera earn at the end of three years

27

Step-by-step explanation:

Simple interest is given by

I = Prt where I is the interest, P is the principle, r is the rate and t is the time

I = 300 * .03 * 3

I =27

27 dollars is made in interest

$27

Step-by-step explanation:

First you need to find 3% of 300 in order to find the annual interest.

3% = 0.03

300 * 0.03 = 9

The annual interest is $9. Now you need to multiply that by 3 to find the interest in 3 years.

9 * 3 = 27

The interest for 3 years is $27.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
