Round to the nearest tenth of a percent

Question

A sofa costing $320.00 is sold for $432.32. Find the markup rate. Round to the nearest tenth of a percent.

Answer 1

Ok. So the amount of the markup is 432.32 - 320.00 = 112.32

Now we need to find the markup rate. (X)

 

320X = 112.32

X = .351 this is 35.1 % 

Since it is already rounded to tenths, leave it as the answer.
