Me with this program in c++ ! computers represent color by combining sub-colors red, green, and blue (rgb). each sub-color's value can range from 0 to 255. thus (255, 0, 0) is bright red. (130, 0, 130) is a medium purple. (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (in other word, equal amounts of red, green, blue yield gray).given values for red, green, and blue, remove the gray part. ex: if the input is 130 50 130, the output is: 80 0 80. thus, find the smallest value, and then subtract it from all three values, thus removing the gray.

Aconsumer would pay an extra they used the rent to own program to buy the computer, rather than using cash. for all of the items, is the cheapest option over the life of the contract. the most expensive overall option is to use purchase the item.

The database design steps are listed below in the incorrect order. choose the correct order number next to each step. determine the information to be stored in the database. determine the fields needed to record the data determine if there will be any repetition of data entered, and separate the fields into tables to normalize the data. create relationships to connect the tables.
