If Alonzo walks 15 miles, What will be the amount of her mother’s donation?
Alonzo's mum donates $10 for participation and an additional $2 per mile.
Alonzo walks 15 miles, this translates to an additional donation of (15×$2) = $30
Total donation by Alonzo's mother = $10 + $30 = $40.

Explanation:
Set up two equations
2
x
+
2
y
=
54
x
×
y
=
176
Solving the first equation for x
2
x
+
2
y
−
2
y
=
54
−
2
y
this gives
2
x
=
54
−
2
y
Divide both sides by 2
(
2
x
2
)
=
54
−
2
y
2
This gives.
x
=
27
−
y
putting this value into the second equation gives.
(
27
−
y
)
×
y
=
176
multiplying across the parenthesis gives
27
y
−
y
2
=
176
subtracting 176 from both sides gives
is
27
y
−
y
2
−
176
=
0
multiplying by negative one gives
−
27
y

y
2
+
176
=
0
factoring this into y gives
(
y
−
11
)
×
(
y
−
16
)
=
0
Solving for both y's gives
y
=
11
,
y
=
16
Since we know the angle 250 and a circle is 360 degrees we can solve for x by subtracting 250 from 360.
360-250=110 degrees.
Tada!
