SOLUTION

The given formula is

[tex]C=p+rp[/tex]

From the given information

[tex]\begin{gathered} P=30.99 \\ r=\frac{5}{100}=0.05 \end{gathered}[/tex]

Substitute these values into the equation:

[tex]C=30.99+0.05\times30.99[/tex]

Solve the equation for c

[tex]\begin{gathered} C=30.99+1.5495 \\ C=32.54 \end{gathered}[/tex]

Therefore, the total cost is:

[tex]\text{ \$}32.54[/tex]
