What expression represents the cost of driving the van for 3 days?

A company rents moving vans for a rental fee of $25 per day with an additional charge of $0.30 mile that the van is driven. What expression represents the cost, in dollars, of driving the van for 3 days and driving it m miles?

---

c = cost

cost = $25 per day + $0.30 per mile

c = $0.30m + 25(3) {cost is $0.30 per mile + $25 per day for 3 days}
c = 0.30m + 75 {multiplied}
