(-2.1) + (-0.1) how do you do this equation? ?

Step-by-step explanation:

A = -2.2

E.

( -2.1 ) + ( - 0.1 )

( -2.1 ) - 0.1. <—— over there, you will see that + is gone and the - has moved down, I done that because + plus with - equals to -.

-2.1

-0.1

———-

-2.2

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
