Number of boxes Caleb lifted = 14
Number of boxes Sergio lifted = 12
Weight of boxes Caleb lifted = c lb
Weight of boxes Sergio lifted = %28c+%2B+10%29+lb
Total number of pounds Caleb lifted = Number of boxes Caleb lifted × Weight
of boxes Caleb lifted
= 14+%2A+c
=+14c
Total number of pounds Sergio lifted =Number of boxes Sergio lifted × Weight of boxes Sergio lifted
= 12%28c+%2B+10%29
Therefore, an expression to represents the total number of pounds Sergio lifted is 12%28c+%2B+10%29
