A fan brings a coupon for 30% off of all food and drink. If she buys a hot dog that normally costs $2.50, how much would she have to pay?

$1.75

Steps: 30%=0.3

0.3 x 2.50 = 0.75

2.50 - 0.75 = 1.75

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.
