Formula


As given
Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.
Here
Approx value = 78.25 in
Exact value = 75.50 in

Error = 2.75
Put in the formula


Error percentage = 3.6 %
Therefore the percentage error is 3.6 % .
Let's set up this problem.

Answer:
$50.08
Step-by-step explanation:
Let x be the cheaper hat, is the more expensive hat is 2 times this value, it can be shown by 2x. The addition of these two values = 75.12
x + 2x = 75.12
3x = 75.12
Divide both sides by three to find 1x:
x = 25.04
If the more expensive hat is 2x this, then:
2 * 25.04 = 50.08
So the more expensive hat is $50.08!
