This is what you do. Y...No worries, Pauline H. :-)<br /><br />This is what you do. You need to make supply [Su(q)] equal demand [De(q)]:<br /><br />Su(q) = De(q)<br /><br />Makes sense? Replace the RHS from equations (1) and (2):<br /><br />AS + BS*q = AD + BD*q<br /><br />Now "isolate" q in the LHS:<br /><br />AS + BS*q - BD*q = AD <--- I just "moved" BD*q to the LHS<br /><br />I'll leave the rest for you to do. Begin by "moving" the other things to the RHS and then factoring q in the LHS. (Just a warning: it may need some simplification.)<br /><br />When you get q "alone" in the LHS you've got the solution: q'. It must be (3).<br /><br />The next step is to find p'. You can use either (1) or (2) (why?). Say, using (2): <br /><br />Su(q') = AS + BS*q'.<br /><br />Just write the solution you found for q' into the RHS of that last equation (look one line above)<br /><br />AS + BS*(solution_you_found) < --- this is what I mean.<br /><br />Likewise, it may need some simplification at the end. The final result must look like (4).<br /><br />If you have any more difficulties, never fear, the Magpie is here!!!Magpiehttps://www.blogger.com/profile/07528637318288802178noreply@blogger.comtag:blogger.com,1999:blog-3634628224045926034.post-37882012359363217872016-10-13T02:21:39.493-07:002016-10-13T02:21:39.493-07:00its me again, magpie. sorry to be a pain. i tried ...its me again, magpie. sorry to be a pain. i tried to get q' & p'. never managed. please explain.<br />- the ooAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3634628224045926034.post-5787795307952107712016-10-06T17:30:01.359-07:002016-10-06T17:30:01.359-07:00Done!

The date &...Good binoculars/eyeballs, Birdwatcher!<br /><br />The date "data" (!) was generated using my spreadsheet's RANDBETWEEN(Bottom, Top) function, for Bottom = 0 and Top = 12. As a matter of fact, all the "data" are random numbers.<br /><br />Twice the same "date" means two sales that day (i.e. day 7 and day 10): say, on day 7 Joe bought 3 widgets, at the price of $1 ea in Sydney; that day Mary, in Brisbane, bought 8, paying $5 apiece. No "date", means no sales that day (days 1 and 9).<br /><br />Should I add a brief note to make that clear to other readers, do you think?Magpiehttps://www.blogger.com/profile/07528637318288802178noreply@blogger.comtag:blogger.com,1999:blog-3634628224045926034.post-68898802464562857552016-10-06T12:51:38.379-07:002016-10-06T12:51:38.379-07:00there are two 7s and two 10s in figure 1, but no 1...there are two 7s and two 10s in figure 1, but no 1 or 9. why?<br />-the ooAnonymousnoreply@blogger.com
