Artif and keisha go to a restaurant for dinner. their meals total $13.75. the tax is 5%. how mush tax is added to the bill?

$13.75 is 100% of the bill
We want 5%
5% out of 100%
5/100 = 1/20
To find 5%, we need to divide by 20
$13.75 / 20 = $0.6875
We can only have 2 decimal places with money, as 7 is above 5 we round 8 up to 9
5% = $0.69

To find the total, add the tax to the original cost
$13.75 + $0.69 = $14.44

3x+9+4x+x=8x+9that's the answer for your question.
