2nd question;
Mary wants to find the horizontal distance between coordinate points (9,4) and (3,4) what can be so to find that distance?

A. Add the x-coordinates
B. Add the y-coordinates
C. Subtract the x-coordinates
D. Subtract the y-coordinates

Explanation:

For the first question, look at the y values. They are 3 and 12. To find the length between those values, subtract and you'll get 9 units.

For the second question, you would subtract the x-coordinates.

* For both of these questions, make sure you know your x and y axes. The    y-axis is always vertical and the x-axis is always horizontal.

Answers:

1. 9 units

2. subtract the x-coordinates

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
