Question

Christian is getting balloons for his grandmother's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Christian wants to get 83 balloons, how many yards of string will he need? 1 foot = 1/3 yard).

Answer 1

Let's begin by listing out the information given to us:

Aim (a) = 9 feets (for each balloon)

`1foot=(1)/(3)yard`

String is sold per yard

Number of balloons (n) = 83 balloons

To get the number of yard of string he needs, we will multiply the amount of string per balloon by the number of balloons. We have:

`\begin{gathered} Amount=aim\cdot number \\ Amount=a\cdot n \\ a=9ft=(1)/(3)\cdot9=3yards,n=83 \\ Amount=3\cdot83=249 \\ Amount=249yards \end{gathered}`
