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?

How would Antonio respondshe would say " u stupid ".

Tess is right about it being easy to find 10% of 46 by moving the decimal point 1 place to the left to get 4.60but there is no need to do that twicebecause if u do 10% twice, ur doing 20%.
okayonce u get 10% of 46 = 4.60then u figure 5% of 46 = (0.05(46) = 2.30because 10% + 5% = 15%then u add those together4.60 + 2.30 = 6.90. This can easily be checked...15% of 46 = 0.15(46) = 6.9 ,just like 10% of 46 + 5% of 46 = 6.9
