An electronics store makes a profit of $32 for every portable dvd player sold and $72 for every dvd recorder sold. The managers target is to make at least $288 a day on sales of the portable dvd players and dvd recorders.

write an inequality that represents the # of both kinds of dvd players that can be sold to reach or beat the target.
let p represent the # of portable dvd players and r represent the # of dvd players

That sign is greater than or equal to, I wasn't sure on how to show it.

288 >/= 32p + 72r

That sign is greater than or equal to, I wasn't sure on how to show it.

Eh, the equation is right, but the sign isn't. The manager wants to make at least $288, so:

288=< 32p + 72r

Because the total price has to be greater than or equal to 288 dollars.
