Q. marx's clothing store is selling a lot of items. On Monday 495 items were sold. On Tuesday 450 items were sold. On Friday 593 items were sold. Marx's misplaced the totals for Wednesday and Thursday, but the average over the five days was 494 items per day. What could have been the totals for Wenesday or Thursday?
A. Do I divide 450 by 3?
Because there are 3 numbers I don't know ;(
495 + 450 + 593 = 1538
494 * 5 = 2470
2470 - 1538 = 932 total for Wed. and Thu.
932/ 2 = 466 average for Wed. and Thu.
