Question

Kira made $391 for 17 hours of work. At the same rate, how many hours would she have to work to make $184 ?

Answer 1

She would have to work 8 hours to make $184.

Answer 2

$\bf \begin{array}{ccll} \ &hours\\ \cline{1-2} 391&17\\ 184&h \end{array}\implies \cfrac{391}{184}=\cfrac{17}{h}\implies h=\cfrac{184\cdot 17}{391}\implies h=8$
