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

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
