Trash is delivered to a dump-site between the hours of midnight (t = 0) and 6 a. m. (t = 6). Selected values of the rate of delivery are shown in the table below, with t measured in hours past midnight, and R(t) measured in tons per hour. Use 4 trapezoids to estimate the total amount of trash rounded up to the nearest ton that is delivered between midnight and 6 a. m. t (hours) 0 1 3. 5 6
R(t) tons/hour 4 2 3 2 1
