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?

Answer 1

sergio lifts 120 pounds

Answer 2

Answer:

$12(c+10)$

Step-by-step explanation:

No. of boxes lifted by Caleb = 14

No. of boxes lifted by Sergio  = 12

Let c represent the weight of each box Caleb lifted.

The boxes that Sergio lifted each weighed 10 lb more than the boxes Caleb lifted.

So, weight of each box lifted by Sergio  = c+10

So, weight of 12 box lifted by Sergio  = $12(c+10)$

Hence expression represents the total number of pounds Sergio lifted is $12(c+10)$
