A delicatessen serves 10 kinds of sandwiches and 5 kinds of chips. How many different sandwich and chip lunches can they make if each lunch has one sandwich and one bag of chips?

To find the total number of different sandwich and chip lunches the delicatessen can make, we need to multiply the number of sandwich options by the number of chip options.

In this case, the delicatessen serves 10 kinds of sandwiches and 5 kinds of chips.

To calculate the total number of lunch options, multiply the number of sandwich options (10) by the number of chip options (5):

10 (sandwich options) x 5 (chip options) = 50

Therefore, the delicatessen can make 50 different sandwich and chip lunches if each lunch includes one sandwich and one bag of chips.
