A blueberry muffin is on sale for 5% off. It's sale price is $1.90. What was the original price?

$2.00

Step-by-step explanation:

The best way to do this here is just use quick calculation.

5% of 1 is 0.05. 5% of 2 would be double that, or 0.1.

2.00 - 0.10 is 1.90.

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.
