Jasmine's credit card has a $2,000 balance that she carried over from last month. assuming her credit card charges an 18 percent
NikAS [45]

Using simple interest, it is found that her interest charge this month will be of $30.

<h3>Simple Interest</h3>

Simple interest is used when there is a single compounding per time period.

The amount of interest after t years in is modeled by:

I(t) = Prt

In which:

  • P is the initial amount.
  • r is the interest rate, as a decimal.

In this problem, considering the time in years, the parameters are:

P = 2000, r = 0.18, t = \frac{1}{12}

Hence:

I(t) = 2000 \times 0.18 \times \frac{1}{12} = 30

Her interest charge this month will be of $30.

Suppose y varies directly as x Write a direct variation
Kamila [148]

Answer:

y=7.5x, y=60

Step-by-step explanation:

you have to consider x as the input and y as output

when input  x=2 the output  y=15  so it grew by 7.5 so we can say that y= 2*7.5

in general the equation is y= 7.5*x

when x=8 we will have y=7.5*8=60

(x+16)°<br> (4x-5)°<br> Find the measure of the angle.<br> I
o-na [289]

4x - 5 = x + 16

Subtract the sides of the equation plus 5

4x = x + 16 + 5

4x = x + 21

Subtract the sides of the equation minus x

3x = 21

Divided the sides of the equation by 3

\frac{3}{3} x =  \frac{21}{3} \\

x = 7

So the measure of the angle equals :

4(7) - 5 = 28 - 5 = 23
