What number results when 42 is increased by 120%?

Answer: 35

We can set up an equation based on the problem: x=value we are tring to find

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

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

\(6*x=210\)

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

\(x=35\)

42 x 120% = 42 x 1.20 = 35

So, start with 42

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

total 77
