Question

1. Julia purchased souvenirs for ten family members and friends while on vacation. She purchased seashells and bracelets for $29.10. If eachseashell cost $2.45 and each bracelet cost $3.60, how many seashells and how many bracelets did she purchase?

`\begin{gathered} x+y=10 \\ x=10-y \end{gathered}`

Substituting, in the first equation,
