Antoine and tess have a disagreement over how to compute a 15% gratuity on $46.00. tess says, “it is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. do that twice. then add the two amounts to get $4.60 + $4.60 = $9.20 for the 15% gratuity.” how should antoine respond to tess’s method?

if 10% = 4.60 then by adding 4.60 to 4.60 he doubled the percent 10% +10% = 20%

 he should have taken half of the 4.60 for the 5% since 5 is half of 10

half of 4.60 = 2.30

 then add them 4.60 +2.30 = 6.90 = 15%

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
