Respuesta :

c/a is the amount they bought so it would be 0.99*c or .99 times the amount they bought same goes to .79a

Answer: 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.
