The answer choices given are confusing. I'll let you figure out the choices.
Answer:
$35.79. I hope this help!!
Step-by-step explanation:
First, we can determine the amount of the tax:
t
=
b
⋅
r
Where:
t
is the amount of the tax.
b
is the amount of the bill - $28.35 for this problem.
r
is the tax rate.
6.25
%
for this problem. Percent or % means per 100 or out of 100. We can write
6.25
%
as
6.25
100
Substituting gives:
t
=
$
28.35
⋅
6.25
100
t
=
$
177.1875
100
t
=
$
1.771875
t
=
$
1.77
Next, we can determine the amount of the tip:
p
=
b
⋅
g
Where:
p
is the amount of the tip.
b
is the amount of the bill - $28.35 for this problem.
g
is the gratuity rate.
20
%
for this problem. Percent or % means per 100 or out of 100. We can write
20
%
as
20
100
Substituting gives:
p
=
$
28.35
⋅
20
100
p
=
$
567.00
100
p
=
$
5.67
Now, we can add the amount of the bill, the tax and tip amounts to find the total cost:
$28.35 + $1.77 + 5.67=$35.79

Answer:
8/14 =(2X-2)/3X
8·3X=14(2X-2)
24X=28X-28
24X-28X=-28
-4X=-28 / ·(-1)
4X=28
X=28:4
X=7
