CD's Word Problem

[greatwhiteshark]

The "We Sell CDs" website plans to purchase ads in a local newspaper advertising their site. Their operating budget will allow them to spend at most $2200 on this advertising adventure. They plan to run at most 20 ads. An ad will cost $50 to appear in the weekday paper and $200 to appear in a weekend edition. Prepare a graph that will represent all of the possible combinations of ads under these conditions.

Well, do it. Where are you struggling?

hey

I think this is a linear inequality problem. I forgot what my teacher said. In any case, I cannot figure out a graph to explain the given data.

The variables are the amount of ads in the weekday paper and the amount of ads in the weekend edition.

Let d = amount of ads in the weekday paper
Let e = amount of ads in the weekend edition

Their operating budget will allow them to spend at most $2200 on this advertising adventure.

Since ads in the weekday paper cost $50 each, and ads in the weekend edition cost $200 each, the total amount of dollars for the ads will be:

. . . . 50d + 200e

So:

. . . . 50d + 200e <= 2200

Can you find the other inequality given?

yes

Thanks to your notes, I can now find another inequality.
