Joe owns a sandwich shop. He charges $10.00 for two sandwiches and one drink and $6.50 for one sandwich and one drink. How much does Joe charge per sandwich? How much per drink?

Answer 1

To find out how much Joe charges per sandwich, we can subtract the cost of the drink from the total cost of a sandwich and the drink.

So, the cost of two sandwiches is $10.00 and the cost of one sandwich is $6.50.

Therefore, the cost of one drink is $10.00 - $6.50 = $<<10-6.5=3.50>>3.50.

This means that Joe charges $6.50 / 1 sandwiches = $<<6.5/1=6.50>>6.50 per sandwich and $3.50 / 1 drink = $<<3.5/1=3.50>>3.50 per drink. Answer: \boxed{6.50}.
