You can work these out the same way I worked out the problems on the other question you asked today. Please check it!
(the —— is just to keep it in place)
x————–21
_____ = ___
64.82 100
x(100) = 64.82 x 21
100x = 1361.22
100x 1361.22
____ = _______
100 100 x = 13.61
64.82 – 13.61 = 51.21 (Thats with the 21 percent discount)
tax
x ———- 4
___ = ___
51.21 100
100x = 51.21 x 4
100x = 204.84
____ = ____
100 100 = 2.0484
51.21 + 2.0484
=53.26 answer
second one
(/ means over a number)
x/2073.00 = 26/100
100x = 2073.00 x 26
100x = 53898
100 divided by 100 = 53898 divided 100
x = 538.98
2073.00 – 538.98 =1534.02
tax
x/1534.02 = 8/100
100x = 1534.02 x 8
100x = 10832.16
100 divided 100 = 10832.16 divided 100
x = 108.3216
1534.02 + 108.3216
answer = 1642.34$
third one
x/162.00 = 7/100
100x = 162.00 x 7
100x = 1134
100 divided 100 = 1134 divided 100
x = 11. 34 = sales tax
fourth one
x/258.00 = 15/100
100x = 258.00 x 15
100 x = 3870
100 divided 100 = 2870 divided 100
x = 28.7
258.00 – 28.7 = 229.3
229.3 + 6.92 = 236.22 $ = answer
i explained them pretty clearly, there is really no other way so I think you can do the last one, but if you really, really really need help i’ll do it.
