Erin is buying produce at a store. she buys c cucumbers at$0.99 each and a apples at $0.79 each .what does the expression 0.99c 0.79a represent?

The total cost ($)

Step-by-step explanation:

Hi, the correct expression is 0.99c+ 0.79a.

This expression represents the total cost for Erin, because the terms are the price of each product (for example cucumber= $0.99) multiplied by the number of products bought (c = number of cucumbers).

Each term equals to the cost of buying a certain quantity of each product, if we add both terms, we obtain the total cost.

Total cost = 0.99c+ 0.79a.

Feel free to ask for more if needed or if you did not understand something.

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 !
