A food truck sells burgers, fries, and sodas. A combo meal costs $10 and consists of one of each item. A frugal family meal costs $30 and consists of four burgers and two orders of fries and two sodas (for sharing). A fry-less family meal costs $28 and consists of four burgers and four sodas. These meals do not have any discounts associated with them. Determine the cost of the individual items.
