Astore is having a sale, each customer receives either a 15% discount on purchases under 100% or a 20% discount on purchases of $100 or more. kelly is purchasing some clothes for $96.60 before the discount. she decides to buy the fewest packs of gum that will increase her purchase to over $100. the price of each pack of gum is $0.79. after the discount, how much less will kelly pay by purchasing the clothes and the gum instead of purchasing only the clothes? (assume there is no sales tax to consider.) this is almost due i mark ! a. $1.05b. $1.67c. $3.69d. $3.87

 b

Step-by-step explanation:

15% of the $96.6 clothes only is $14.49

in order to get over 100 dollars kelly would have to purchase 5 packages of gum

5 times .79 = $3.95

With the gum the total would be $100.55 divided by 20% = $20.11

$20.11 - $14.49 = $5.62  however you need to subtract the price of the gum also

$5.62 - $3.95 = $1.67

b

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
