Answer: 35

 

We can set up an equation based on the problem:

x=value we are tring to find

 

\(\frac{120}{100}*x=42\)

\(\frac{6}{5}*x=42\)

\(6*x=210\)

\(x=\frac{210}{6}\)

\(x=35\)

 

What number results when 42 is increased by 120%?    

 

42 x 120%  =  42 x 1.20  =  35           

 

                      So, start with 42    

               and increase it by 35      ( "increase" means make it bigger )   

                                   total  77
