[1/1 Formula]
    Work: Calculate the value of equation 1.9782×(2.2×40+6.8×65+4.9×80+1.1×130)+0.28×6200×0.31 .
    Question type: Mathematical calculation
    Solution:
          1.9782×(2.2×40+6.8×65+4.9×80+1.1×130)+0.28×6200×0.31
        =1.9782×1065+0.28×6200×0.31
        =2106.783+0.28×6200×0.31
        =2106.783+1736×0.31
        =2106.783+538.16
        =2644.943

    Answer:1.9782×(2.2×40+6.8×65+4.9×80+1.1×130)+0.28×6200×0.31=2644.943
