Shawn the builder estimated that it would cost $12,000 to build a new conservatory. In fact it cost $13,200 What was the percentage error?

Respuesta :

Answer:

10%

Solution,

Measured value= $ 13200

True value = $ 1200

Now,

Percentage error:

[tex] \frac{measured \: value - true \: value}{true \: value} \times 100 \: percent\\ = \frac{13200 - 12000}{12000} \times 100 \: percent \\ = \frac{1200}{12000} \times 100 \: percent \\ = 10 \: percent[/tex]

Hope this helps...

Good luck on your assignment..
