Question

12. Charlie's Pancake House has decided to increase all of its menu prices by 8%. Let

x represent the original price of an item on the menu. Which expressions can the owner
use to calculate each item's new menu price?
Select two answer choices.

Answer 1

When we represent a percent in decimal format, we simply need to divide the percent by 100. In this case we would want to add 100% first to get 108%, as we are getting a price that is 8% higher. The decimal would be 1.08.

To calculate the new prices you would use the equation p = 1.08x

You said select two answer choices, but I’m not sure if you mean two ways of answering.

I suppose you could divide x by (1.0 / 1.08) by doing x (1.0 / 1.08)^-1, but I don’t think that would be a rational way of doing this.

Hope this was helpful.
