Judith has \$70 in a savings account that earns 5% interest , compounded annually .
Firlakuza [10]

Answer:

$81.03

Step-by-step explanation:

Given

n = 1 --- annually

t =3 --- time

r = 5\% --- rate

PV = \$70 ---- Present value

Required

The future value

This is calculated as:

FV = PV * (1 + \frac{r}{n})^{nt}

This gives:

FV = 70 * (1 + \frac{5\%}{1})^{1*3}

FV = 70 * (1 + 5\%)^3

FV = 70 * (1.05)^3

FV = 70 * 1.157625

FV = 81.03375

<em>The future value to the nearest cent is: $81.03</em>

5|2x - 3| + 4 = 9<br> How do you solve this
agasfer [191]

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

<u>Solution 1</u>

(10x-15) + 4 = 9

10x -11 = 9

10x = 20    -> x = 2

<u>Solution 2</u> (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10      -> x = -1

Please correct me if I'm wrong.
