The cost of a 3 minute cell phone call is $\$ 0.18$. At the same rate per minute, what is the cost of a 10 minute call?
(A) $\$ 0.30$
(B) $\$ 0.60$
(C) $\$ 1.80$
(D) $\$ 5.40$
(E) $\$ 6.00$
Since a 3 minute phone call costs $\$ 0.18$, then the rate is $\$ 0.18 \div 3=\$ 0.06$ per minute.

For a 10 minute call, the cost would be $10 \times \$ 0.06=\$ 0.60$.

ANSWER: (B)
