\bf \begin{array}{llll}
\cfrac{v}{r}=w\\\\
v=\cfrac{s}{t}
\end{array}\qquad
\begin{cases}
v=\textit{linear speed}\\
r=radius\\
w=\textit{angular speed}\\
s=\textit{arc's length}\\
t=\textit{time length} \\----------\\
r=6\\
s=14.13\\
t=3
\end{cases}\implies \cfrac{\frac{s}{t}}{r}=w

Kate bought a T-shirt for $12.95 and a pair of shorts for $10.95. She paid 6.25% in tax. What is her total amount that she paid?
sergeinik [125]

Kate paid $25.39 for her purchases.

Kate will receive $24.61 in change.

Step-by-step explanation:

Given,

Cost of t-shirt = $12.95

Cost of pair of shorts = $10.95

Total = cost of t-shirt + cost of pair of shorts

Total = 12.95 + 10.95 = $23.90

Sales tax = 6.25% of total amount

Amount of sales tax = \frac{6.25}{100}*23.90=\frac{149.375}{100}

Amount of sales tax= $1.49

Total amount with sales tax = 23.90 + 1.49 = $25.39

Kate paid $25.39 for her purchases.

Amount paid = $50

Change received = Amount paid - Bill amount

Change received = 50 - 25.39 = $24.61

Kate will receive $24.61 in change.
