Answer 1

We know that

• The sale price is $312.

,

• The desk is 35% off.

We just have to divide to find the regular price. Remember that 35% is equivalent to 0.35. It's important to notice that $312 represents 65% of the regular price since is 35% lower. Now, we use the rule of three: If $312 represents 65%, how much would represent 100%?

`x=(312)/(0.65)=480`

Therefore, the regular price is $480.
