If 28% of a sum is 100.80 what is the sum

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
