The answer depends on the tax rate and since you have not shared that crucial bit of information, it cannot be answered. However, if you find the tax, say it is 21%. You divide by 100, multiply by (100+21) and this gives total plus tax.
21
21+21+19+19=80
21+21+17=59
(21-21)+(21-21)+21 = 0+0+21 = 21

21 and 825/1000
63
6 + 3 + 21 + 63 + 21 = 114
21
21+21+19+19=80
21+21+17=59
(21-21)+(21-21)+21 = 0+0+21 = 21
55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
The answer to 21 plus 16 is 37.
25 plus 21 plus 19 is equal to 65.
