Keeping in mind that 5 months is not even a year, since there are 12 months in a year, then is really just 5/12 of a year, therefore

$\bf ~~~~~~ \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$6600\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=years\to &\frac{5}{12}
\end{cases}
\\\\\\
A=6600\left( 1+0.04\cdot \frac{5}{12} \right)\implies A=6600\left( 1+\frac{1}{60} \right)\\\\\\ A=6600\left( \frac{61}{60} \right)$

Julie goes to the sports store and spends $40.50 before tax. She buys a pair of shorts for $21.75 and 3 pairs of socks that each

Nastasia [14]

Answer: Cost price of each pair of socks is $6.25.

Step-by-step explanation:

Given: The total amount spent by Julie before tax= $40.50

Cost price of a pair of shorts =$21.75

Now, Cost price of 3 socks = $\$40.50-\$21.75=\$18.75$

Therefore, Cost price of 3 socks =$18.75

Let x be the cost price of each pair of socks.

$\Rightarrow3x=18.75\\\Rightarrow\ x=\frac{18.75}{3}\\\Rightarrow\ x=6.25$

Hence, cost price of each pair of socks is $6.25.
