Response;
- The amount that they spent at the dell is $16

Given;
The number of Toby's friends = 3
Number of people that ate lunch, n = Toby + His friends = 1 + 3 = 4

The expression that gives the amount Toby and his friends spend altogether is therefore;
Amount spent = n × (Cost of a sandwich + cost of a drink)
