An electronic store makes a profit of $25 for every portable dvd player sold and $55 for every dvd recorder sold the managers target is to make at least $225 a day on sales of the portable dvd players and dvd recorders write an inequality that represents the number of both kinds of dvd players that can be sold to reach orbit the cells target let p represent the number of portable dvd players and r represent the number of dvd recorders

Step-by-step explanation:

P = number of portable DVD players; profit: $25 each

R = number of DVD recorders; profit $55 each

Profit for all portable DVD players sold: 25P

Profit for all DVD recorders sold: 55R

Total profit: 25P + 55R

Since you want the profit to be at least $225, at east $225 means $225 or more, so we use teh greater than or equal to symbols.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

answer: it's d
