Question

Maxwell earns $99 for every 5.5 hours for work. How much will he earn if he works 30 hours this week (hint: find the unit rate, then multiply by 30 hours)

Answer 1

$\bf \begin{array}{ccll} \ {data-answer}amp;hours\\ \cline{1-2} 99&5.5\\ x&30 \end{array}\implies \cfrac{99}{x}=\cfrac{5.5}{30}\implies 2970=5.5x\implies \cfrac{2970}{5.5}=x\implies 540=x$
