I need help solving this problem
The percent of geometry in the spring is how much greater than the percentage of history students thay took history in the spring?
Geometry in the spring 32
History. In the spring 20

Respuesta :

the students who took History were 20, while there were 32 Geometry students, how many more Geometry students?  well 32 - 20, just 12 more.

now, if we take 20 to be the 100%, how much is 12 off of it in percentage?

[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 20&100\\ 12&p \end{array}\implies \cfrac{20}{12}=\cfrac{100}{p}\implies p=\cfrac{12\cdot 100}{20}[/tex]
