Maria wants to buy a shirt that cost $75. If she has a coupon for 45% off, how much money will she save? Use a proportion to solve this problem. PLEASE ONLY ENTER THE NUMBER - DO NOT ENTER UNITS (no $). *

33.75

Step-by-step explanation:

45 : 100 = 0.45

75 x 0.45 = 33.75

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.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
