Rosie is saving money. She has $\$ 120$ in her account today and will begin saving by making $\$ 30$ deposits into her account. If she makes $m$ such deposits, the expression that best represents the number of dollars in her account is
(A) $120+m$
(B) $30 \mathrm{~m}$
(C) $30+120 \mathrm{~m}$
(D) $150 \mathrm{~m}$
(E) $120+30 m$
If Rosie deposits $\$ 30$ each month for $m$ months, she will save $30 m$ dollars.

Rosie has $\$ 120$ in her account today, and so after $m$ deposits Rosie's total savings (in dollars) is best represented by the expression $120+30 \mathrm{~m}$.

ANSWER: (E)
