Okyerefo Company Ltd. manufactures okyerefo soap. The product is sold in three com- munities, X, Y and Z. The supply function schedules of the three communities as well as that of the entire market supply for okyerefo soap are shown below. Unit Price 100 250 Community X 520
725
Community Y 640
850
Community Z 700 1000
Market Supply 1860 2575
Use the information in the table to estimate
i. the supply equations of each of the three communities.
ii. the market supply function.
iii. market supply when the price decreases to 50

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

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
