I was wondering if someone could confirm what I'm doing is right.

Situation: You want to buy three books that are on sale at 20% off. The original prices of the books are $2.50, $4.95, and $6.00. How much will you save?

We have to do one with distribution and without and I don't know if the distribution one I'm doing is right. I have

2($2.50+$4.95+$6.00)

$2.50+$6.00 = $8.50

$8.50+$4.95 = $13.45

0.2*$13.45 = 2.69

and I don't know how to do it without distribution so I was wondering if I could get help on that as well :)

I think you got it correct but here is the what I think they are asking

0.2(2.5-4.95+6)    =     0.2*2.5+0.2*4.95+0.2*6    =    2.69

2.5	  x    0.2	 =  0.5
4.95	  x    0.2	 =  0.99
6	  x    0.2	 =  1.2
		              2.69  sum of individual discounts
13.45  x    0.2	 =  2.69
sum of books at retail
