Mrs. Gabriel's monthly salary is Php 18,000 plus a 7% commission on her sales. If she wants to earn at least Php 25,000 a month, what must be the amount of her sales?

18000 of it was her salary.

that leaves 3000 commission.

3000/.12 = 25000.

she made sales of 25000.

the formula for her pay would be pay = 18000 + .12 * sales

if sales is 25000, then formula for pay becomes:

pay = 18000 + .12 * 25000

simplify to get:

pay = 18000 + 3000

combine like terms to get:

pay = 21000

Mark my answer as brainalist please

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
