Answer:
If
y
varies directly with
x
, then
y
=
m
x
for some constant
m
We are told that this relation holds for
(
x
,
y
)
=
(
5
,
10
)
so
10
=
m
⋅
5
→
m
=
2
and our direct variation equation is
y
=
5
x

Answer: 77.5%
Step-by-step explanation:
1 liter is about 0.264172 gallons. Thus, simply multiply 170,000*0.264172 to get about 44,909.25 gallons. Then, do 200,000-44,909.25 to get 155090.75. Then do 155090.75/200,000 to get that the tank has 0.77545375, or about 77.5% fuel remaining.
