Respuesta :

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

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

[tex]1foot=\frac{1}{3}yard[/tex]

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:

[tex]\begin{gathered} Amount=aim\cdot number \\ Amount=a\cdot n \\ a=9ft=\frac{1}{3}\cdot9=3yards,n=83 \\ Amount=3\cdot83=249 \\ Amount=249yards \end{gathered}[/tex]
