Step: Solve
3
x

4
y
=
2
for x:
3
x
−

y
=

+
4
y
(Add 4y to both sides)
3
x
=
4
y
+

(Divide both sides by 3)
x
=

Answer:
Infinitely many solutions.
C = Cost ($)
m = Miles driven {m≥100}
d = Rental days
---------------
Use this formula if m≥100:
C = 36 * d + 0.5 * (m - 100)
Use this formula if m<100:
C = 36 * d
Since the groups are split into 4, you would do 16/4 to get 4 songs in each group. 3 groups would equal 12 songs because 3*4 is 12. 12 of her songs are pop
