Question

Caleb and Sergio stacked boxes on a shelf. Caleb lifted 14 boxes and Sergio lifted 12 boxes. The boxes that Sergio lifted each weighed 10 lb more than the boxes Caleb lifted.
Let c represent the weight of each box Caleb lifted.

Which expression represents the total number of pounds Sergio lifted?

c + 10

120c

10(c−12)

12(c+10)

Answer 1

each box weighed 10 more pounds 

and he lifted 12 boxes

 so if you multiply 12 x the weight and then 12 times 10 more pounds each you would have 12c +12*10

which uses the equation 12(c+10)

Answer 2

Answer:

12 c+10
