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.

Which expression represents the total number of pounds Sergio lifted?
Let c represent the weight of each box Caleb lifted.

Answer 1

14 ( c ) = Caleb's

12 ( c + 10 ) = Sergio's

Explanation:

Caleb lifted 14 boxes so you multiply 14 by c which is the weight of each box and for Sergio he lifted 12 boxes although his weighed 10 pounds more so you add 10 to c which would equal c + 10 multiplied by 12
