Answer:

$p=\$1.50,\\c=\$0.75$

Step-by-step explanation:

We can write the following system of equations:

$\begin{cases}3p+2c=6.00,\\2p+3c=5.25\\\end{cases}$

Multiply the second equation by $-\frac{3}{2}$ to isolate and solve for $c$ :

$\begin{cases}3p+2c=6.00,\\-3p-4.5c=-7.875\\\end{cases},\\-2.5c=-1.875,\\c=\fbox{$\$0.75$}$ ,

Now plug in $c=0.75$ into any equation to solve for $p$ :

$3p+2(0.75)=6.00,\\3p=4.50,\\p=\fbox{$\$1.50$}$ .
