Question

A sofa IS on sale for $639, which is 29% less than the regular price. What is the regular price?X

Answer 1

$900

Explanation:

To calculate the regular price, we must take into account that the price on sale is equal to the regular price minus the discount, knowing this, we can formulate the following equation:

`x-x\cdot 0.29=639`

Let x be the regular price, we solve for x, like this:

`\begin{gathered} 0.71x=639 \\ \\ x=(639)/(0.71) \\ \\ x=900 \end{gathered}`

The regular price of the sofa is $900
