Question

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?

Answer 1

10%

Solution,

Measured value= $ 13200

True value = $ 1200

Now,

Percentage error:

`(measured \: value - true \: value)/(true \: value) * 100 \: percent\\ = (13200 - 12000)/(12000) * 100 \: percent \\ = (1200)/(12000) * 100 \: percent \\ = 10 \: percent`

Hope this helps...

Good luck on your assignment..
