A student's pay of $21 an hour is $6 more than twice the amount the student earns per hour at an internship. Enter and solve an equation to find the hourly pay of the internship.

Respuesta :

w = amount she earns for her work.

twice that is 2*w, or 2w.

6 more than that is 2w + 6.


[tex] \bf 21~~\stackrel{is}{=}~~\stackrel{\textit{twice her earnings + 6}}{2w +6}\implies 15=2w\implies \cfrac{15}{2}=w\implies 7\frac{1}{2}=w [/tex]
