The table is as follows:

Price-$2.00 # sold was 16

-$2.50 13

-$2.75 12

-$3.00 10

-$3.50 7

I used (2.00,16) & (3.00, 10) to get the prediction equation y=-6x + 4 but do not know how to solve for the # of books sold when the price is $4.50.

**drwls**, Sunday, January 6, 2008 at 11:48amThe relationship between price and number sold is not quite linear. If you choose prices of = = 2.50 and 3.50 to get a prediction equation, the straight-line fit would be

y = 28 - 6x

Then if x = 4.50, the number sold is

y = 28 - 27 = 1
