3. suppose you are buying a $30 pair of shoes that are discounted 20%. how much will you pay for the shoes?

$24

Step-by-step explanation:

calculate 20% of $30 and subtract the discount from the cost price

20% = = 0.2, hence

discount = 0.2 × $30 = $6

buying price = $30 - $6 = $24

$24

Step-by-step explanation:

To determine the discount, we take the price of the shoes and multiply by the discount rate

Discount = 30 * .2

Discount = 6

The new price is the original price  minus the discount

new price = 30-6

New price = 24

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
