The only possible answer could be $200 because all other answers are more or less than $20 which would be 10% of the percent error. But due to there error being less than 10% the only reasonable answer is $200.

Ok.

You predicted that your tip will be $200.

You realised that you were wrong by less than 10%.

So,

10% of $200

= (10/100) × $200

= $20

So, your actual tip can be less or more by less than $20.

$160 (less than $200 by $40, so error = 20%)

$180 (less than $200 by $20, so error = 10%)

$200 (equal to $200, so error = 0%)

$220 (more than $200 by $20, so error = 10%)

$240 (more than $200 by $40, so error = 20%)

So, your possible actual tips can be:

$200 (equal to $200, so error = 0%)

Hope it helps!!!

Have a great day. ^_^
