Three towns x, Y and z are such that y is 20km for x and 22km from z. town x is 18km from z. A health center is to be built by the government to serve the three towns. The center is to be located such that patient s from x and y will always travel equal distance to access the center while patient from z will travel exactly 10km to reach the center

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

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

y = -1

x = 8

hope this !
