Question

An electronics store makes a profit of $61 for every standard CD player sold and $66 for every portable CD player sold. The managers target is to make at least $405 a day on sales from standard and portable CD players. write an inequality that represents the numbers of both kinds of CD players that can be sold to reach or beat the sales target. Lets s represent the number of standard CD players sold and p represent the number of portable CD players sold. then graph the inequality.

Answer 1

61 for every standard cd player, so, sales is:

61s

66 for every portable cd player, so, sales is:

66p

At least $405 means 405 or more, we can represent this as:

$61s+66p\geq405$

By making "s" be the x-axis and "p" be the y-axis, we can graph this line.

Since it's an inequality that is greater than or equal to, we shade the region "above" the line.
