Question

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet. What is Ruiz's percentage error?
(How do you solve this?)

Answer 1

First, subtract the two values:

16 - 15.4 = 0.6

Now divide this to the actual area:

0.6 / 15.4 = 0.038961039

Multiply by 100:

0.038961039 * 100 = 3.8961039

So the percent error is approximately 3.9%

Answer 2

Answer:3.9%

Step-by-step explanation:

16-15.4=0.6

0.6/15.4=3.89610

3.89610*100%=3.9%
