Answer:
<u>R8000</u>.
Step-by-step explanation:
First, let's calculate the amount they are going to have to pay the bank after 1 year. It is given by the following expression:
R5 000 * 1.28= R6400
Therefore, they have to pay R6400/12 monthly.
Now, in fifteen months the total amount to pay should be (R6400/12) * 15= <u>R8000</u>.

Answer:

Step-by-step explanation:
To write the quadratic in standard form, begin by writing it in vertex form

Where (h,k) is the vertex of the parabola.
Here the vertex is (-3,-2). Substitute and write:

To find a, substitute one point (x,y) from the parabola into the equation and solve for a. Plug in (0,7) a y-intercept of the parabola.

The vertex form of the equation is
.
To write in standard form, convert vertex form through the distributive property.
