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.
