Question

Which equation can Pablo use to find p the regular price of the shirt

Answer 1

The final price of the shirt is given by the regular price minus the discount value. Since the final price is $28, the regular price is p, and the discount is $16, the equation is

`p-16=28`

If we add 16 to both sides of the equation, we have

`\begin{gathered} p-16+16=28+16 \\ p=28+16 \end{gathered}`

If we invert the order of the equality, we get the last option as the answer

`16+28=p`
