A handyman quoted me by saying, "We charge $40.00 per hour." He worked 3.5 hours, so how much is owed to him?

I needed some very simple roof repair done (a handful of shingles replaced). The handyman quoted me the rate by saying, "We charge $40.00 per hour." It was understood that he would be bringing another person with him to help him. If took them 3.5 hours (working together) to complete the job, what is the total amount due?
