Ang Pamimili at Pagbibili ng mga Paninda sa

Kooperatiba

- Ibinabatay sa pangangailangan ng mga kasapi ang mga paninda

sa isang tindahang kooperatiba.

Mga Dapat Isaalang-alang sa Pamimili ng mga

Paninda

a. Ang pamumuhay ng mag-anak sa pamayananb.Ang dami ng mag-anak na naninirahan ditoc. Ang kanilang pinagkukunand.Ang mga kaugalian sa pamimili

- Ang mga panindaang bibilhin ay dapat nababatay sa uri ng tindahang kooperatibang itinatag.

- Ang paninda ay dapat mataas ang uri at mababa ang halaga.- Sa pamimili ng mga paninda, dapat alamin ang mga lugar at oras ng bilihan o bagsakan ng mga paninda.

- Ang mga paninda ay dapat bilhin nang maramihan o pakyawan upang kumita sa pagtitinda.- Gumawa ng talaan ng bibilhin.

- Kung ang mga paninda ay hango o galing sa pabrika at ihahatid ng trak o ahente, suriin muna ang mga paninda bago pirmahan ang resibo (delivery receipt).

- Itago ang mga resibo dahil dito ibabatay ang gagawing imbentaryo.

Area of a Trapezoid

A trapezoid is a 4-sided figure with one pair of parallel sides. For example, in the diagram below,

the bases are parallel. To find the area of a

trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then divide the result by 2. The formula for the area of a trapezoid is:

A = 12 (b1 + b2) h

orA = (b1 + b2) x h ÷ 2

Each base of a trapezoid must be perpendicular to the height. In the diagram above, both bases are

sides of the trapezoid. However, since the lateral sides are not perpendicular to either of the bases, a dotted line is drawn to represent the height.

Example:Find the area of a trapezoid with bases of 10 inches and 14 inches, and a height of 5 inches.

Solution:A = (b1 + b2) x h ÷ 2

= (10 + 14) x 5 ÷ 2 = 24 x 5 ÷ 2 = 120 ÷ 2

= 60 square inches Solve:1. Find the area of a
