Arestaurant has two appetizer specials. tomato bread costs $5.50, and stuffed mushrooms cost $6.75. the total amount in sales from the two appetizers on a friday night was $186.75. which equation can be used to represent x, the number of stuffed mushroom orders and y, the number of tomato bread orders?

Hey there!

First of all, since we don't know the exact number of orders for each appetizer, we can have an equation but we wouldn't have an answer. We know that we have to set it equal to 186.75, because that's our total amount of orders.

Since we know the prices of each appetizer, we can multiply that price by the number of orders (their assigned variables) and set it equal to the total to get:

5.50y + 6.75x = 186.75

Notice how we multiply the price by the number of orders. This is because, for example, if each mushroom cost 5 dollars, we'd multiply 5 by the number of orders.

Hope this helps!
