Answer: [tex]\$12.50[/tex]Step-by-step explanation: The complete exercise is: "At the cocession stand, medium sodas cost $1.25 and hot dogs cost $2.50. Jack bought 2 medium sodas snd 2 hot dogs. He paid with $20. What was his change?" You need to analize the information provided in the exercise. You know that the price of a medium soda was: [tex]Medium\ soda=\$1.25[/tex] And the price of a hot dog was: [tex]Hot\ dog=\$2.50[/tex] Therefore the total amount of money Jack spent in 2 medium sodas and 2 hot dogs, was: [tex]Total=2(\$1.25)+2(\$2.50)\\\\Total=\$7.50[/tex]  Since Jack paid with $20, you need to subtract the total amount of money calculated before from $20, in order to calculate his change. Therefore, you get that Jack's change was: [tex]Change=\$20-\$7.50\\\\Change=\$12.50[/tex]
