**Answer:**

**The correct option is: C. Add the two bags together, multiply by .80, and then subtract $1.00.**

**Step-by-step explanation:**

First you need to __add the prices of two bags__ for getting the total sales price.

Now, the store is offering 20% off, that means you __need to pay 80% of the total sales price__. For finding the amount, we need to __multiply the total sales price by 0.80__

Then, you have a manufacturers coupon for a $1.00 off. So, for fining the final price, you need to __subtract that $1.00 from the last result__.

**Thus, the correct option will be……**

**C. Add the two bags together, multiply by .80, and then subtract $1.00.**
