During the week, employees at a company spend more and more time for eating lunch. The table below gives the time (in minutes) that the employees spend eating lunch during one week, but the data for Thursday is missing. Using the rest of the data table, interpolate how many minutes the employees would have spent eating lunch that day.

We know that every day, employees spend more time eating, so the time spend eating on Thursday would have to be more than the time on Wednesday, but less than the time on Friday. The only value that fits this is 35 minutes.
