Simplify the expression
4+3(x+5)

4+(3xX)+(3x5)

Step-by-step explanation:

So let's take out the 4 for right now. You're left with 3(x+5) the parenthesis are saying to multiply the 3 with x (3x) and add it to the answer of 3x5 (15). Because you do parenthesis before addition (Parenthesis Exponents Multiplication Division Addition Subtraction) you complete that and add back the 4 in to the problem.

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.
