Answer:

$79.99

Explanation:

The error is in step 3. He needed to ADD 72.50 to both sides of the equation. Instead, he added 72.50 to the left side and subtracted 72.50 from the right side.

Correction calculation

5(r - 14.50) = 327.45

5r - 72.50 = 327.45

5r = 399.95

r = 79.99

The regular price is $79.99

Answer:

$79.99

Correct method:


\rightarrow \sf 5(r-14.5)=327.45


\rightarrow \sf 5r-72.5=327.45


\rightarrow \sf 5r=327.45+72.5


\rightarrow \sf 5r=399.95


\rightarrow \sf r=(399.95)/(5)


\rightarrow \sf r=79.99

The regular price is $79.99
