Solve for p by simplifying both sides of the equation, then isolating the variable.
p= - 7/3
Lets organize out the numbers and calculate them,
so .....
Country music cd is $12
Rock music cd is 12× 2/3 = $8
Platinum edition cd is $8 x 2 = $16
add up all of the final numbers
<span>16+12+8 = $36
Your answer is
$36 </span>
A=((40+64)/2)*18= 936 units^2
