First we must calculate how much Kelly will pay for the original purchase of $96.60. With 15% off, she will only need to pay $82.11.

Next we must figure out how much gum Kelly will buy to make $96.60 go over $100, and it turns out that 5 packs of gum will be the fewest to make her qualify for the 20% discount.

Buying 5 packs brings Kelly's total up to $100.55 and with a 20% discount she will end up paying $80.44 instead.

Subtract the higher amount ($82.11) by the lower amount ($80.44) aka [$82.11 - $80.44] and we are left with a difference of $1.67

By buying the 5 packs of gum Kelly will save $1.67

What is the equation of the line that passes through each pair of points in slope-intercept form?

Ivanshal [37]

First, you need to use the points to come up with a m (slope). To do this you must use the equation m= y2-y1/x2-x1. label the x in one pair of coordinates x1 and the y, y1. Then label the other x in the other pair of coordinates x2 and the y, y2. use the equation and figure the slope. Next, put the easiest coordinates into point-slope form. The equation you are to use is... y-y1=m(x-x1). Input the values and then distribute the m inside the parenthesis. Then you should be able to do the rest. The final product should be in slope-intercept form.

If u = <-7, 6> and v = <-4, 17>, which vector can be added to u + 3v to get the unit vector <1, 0> as the resu

ivann1987 [24]

With u = <-7, 6> and v = <-4, 17>, we have

u + 3v = <-7, 6> + 3 <-4, 17> = <-7, 6> + <-12, 51> = <-19, 57>

We want to find a vector w such that

u + 3v + w = <1, 0>

Subtract u + 3v from both sides to get

w = <1, 0> - (u + 3v) = <1, 0> - <-19, 57>

w = <20, -57>

Sometimes the unit price on two sizes of the same product will be the same. When this is the case, how will different kinds of d

mamaluj [8]

The different type of discount effected on the prices of two similar products having the same unit price may either increase or decrease the total unit price on the discounted sale price of the items.

Taking an hypothetical scenario :

50 ml of Product A = $100

60 ml of product A = $100

<u>Discount on sale of 60ml size on purchase of two or more units </u> : 10% off

Discounted price of 60 ml size :

Initial product cost on purchase of 3 units = ($100 × 3) = $300

Discounted price = (100 - 10)% × $300 = $270

<u>Discount on sale for 50ml size on purchase of two or more units</u> : $20 off

Discounted price of 50ml size :

This means $20 is deducted from any purchase of two or more units ;

Hence, purchasing 2 units of the 50 ml product will cost ; (

($100 × 2) - $20

$200 - $20 = $180

Therefore, the discount effected on the cost of product which has the same unit price may either decrease or increase the total cost of one product relative to the other.
