\bf \textit{circumference/perimeter of a circle}\\\\ C=\pi d~~ \begin{cases} d=diameter\\[-0.5em] \hrulefill\\ C=314 \end{cases}\implies 314=\pi d\implies \cfrac{314}{\pi }=d \\\\\\ \stackrel{\textit{using }\pi =3.14}{\cfrac{314}{3.14}=d}\implies \cfrac{314}{~~\frac{314}{100}~~}=d\implies \cfrac{\underline{314}}{1}\cdot \cfrac{100}{\underline{314}}=d\implies \boxed{100=d}

Courtney had $55 to spend at the fair. She paid $22.50 for rides and $14.25 for lunch and snacks. Courtney says she has $18.25 l
IrinaVladis [17]
She has $55. She spent $22.50 on rides so now she has $32.50 . Then she spends $14.25 on lunch and snack so now she has $18.25.


A. would be wrong because Courtney IS correct, she has $18.25 left.

C. is also wrong because, again, Courtney IS correct.

So the only option left is B and it explains why Courtney is correct.

Option B is the correct answer.

Hope this helps.
