The Jones family plans a trip to the amusement park and purchase a family package for $280.00. They also want to buy lunch and souvenir cups. The chicken platter costs $8.50 each and the burger platter costs $9.50 each. The souvenir cups each cost $10.00, which includes unlimited refills. Mr. and Mrs. Jones have a budget and are trying to decide who will order which platter and who will buy a souvenir cup. Let x represent the number of chicken platters, y represent the number of burger platters, and z represent the number of souvenir cups. Which of the following algebraic expressions can be used to describe the amount of money the Jones family will spend, before sales tax, based on the number of each meal and souvenir cups they purchase?

The amount of money spent on chicken platters will be $8.50 multiplied by the number of chicken platters (x).

The amount of money spent on burger platters will be $9.50 multiplied by the number of burger platters (y).
The amount of money spent on souvenir cups will be $10.00 multiplied by the number of souvenir cups (z).

Therefore, the algebraic expression that can be used to describe the amount of money the Jones family will spend, before sales tax, based on the number of each meal and souvenir cups they purchase is:

8.50x + 9.50y + 10.00z
