Whats the expression 2.6c+1.8c+2.75

4.4c+2.75

Step-by-step explanation:

With the expression we have before, to simplify it we have to combine the like terms. There are two terms with the variable c in in, so we can add 2.6c & 1.8 c which equals 4.4c. There is no other term like 2.75, so we leave that be.

Hope this helps!

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 !
