Answer: Beth have 144 inches.
Step-by-step explanation: Given that Beth bought 4 yards of ribbon.
We are to find the number of inches of ribbon that Beth have.
We know that
1 yard = 36 inches.
Therefore, we get
[tex]4~\textup{yards}=4\times36~\textup{inches}\\\\\Rightarrow 4~\textup{yards}=144~\textup{inches}.[/tex]
Thus, Beth have 144 inches.
