Question

Ellie bought snacks for her team's practice. She bought a bag of popcorn for $3.47 and a 10-pack of juice bottles. The total cost before tax was $23.47. Write and solve an equation which can be used to determine jj, how much each bottle of juice costs.

Answer 1

b = juice bottle price

$\stackrel{\textit{one bag of popcorn}}{3.47} + \stackrel{\textit{10 juice bottles}}{10b} = \stackrel{\textit{before tax}}{23.47} \\\\\\ 10b = 23.47-3.47\implies 10b = 20\implies b=\cfrac{20}{10}\implies \stackrel{\textit{two bucks}}{b = 2}$
