## Algebra 1

The percent is $1333.\overline3\%$.
Plug the values into this equation, where b is one value, p is the percent, expressed as a decimal, and a is p percent of b. $a=p\%\times b$ substitute $400=p\%\times30$ divide both sides by 30 $400\div30=p\%\times30\div30$ simplify $13.\overline3=p\%$ convert from a decimal to a percent $1333.\overline3=p\%$
