Answer:
x = 70
Step-by-step explanation:
180 - 112 = 68
2x + 2x + 12 + 68 = 360
4x + 80 = 360
4x = 360 - 80
4x = 280
x = 280/4
x = 70
2x = 2*70 = 140
2x + 12 = 2*70 + 12 = 152
180 - 140 = 40
112 + 40 = 152
180 - 152 = 28
112 + 28 = 140

Answer:
<h2>$99.84</h2>
Step-by-step explanation:
Step one:
given data
we are told that before tax the bill is pretax= $78
the tax is 8%
and he left 20% of the pretax for the attendant.
Step two:
let us find the amount he paid for eating with tax
=8/100*78
=0.08*78
=$6.24
with tax the meal cost is
= 78+6.24
=$84.24
let us solve for the tip he left (note: it is 20% of the pretax)
=20/100*78
=0.2*100
=$15.6
the tip is $15.6
Step three:
<u>the total amount he paid after eating plus tax and tip is </u>
78+6.24+15.6
=$99.84
