Keep in mind that x, y, and z each represent different things as listed above.
If you take a tally of each letter represented above, you will have a count of Manaya's order.

Manaya's friend Conner wanted to find the cost of Manaya's drinks on her trip to Quick and Cheap Drive-Thru.
He used the expression x + x + x to represent this. Can you use this expression and complete it to include all of Manaya's order?

The correct expression is x + x + x + y + y + z + z + z + z. This can also be simplified to equal 3x + 2y + 4z.

Manaya bought three drinks that each cost $0.79. How much did she spend on drinks?
Now calculate how much she spent on sandwiches and potatoes to find the total cost of her order.
