Rose is thinking about getting a cell phone. One cell phone plan costs 10 cents per minute plus a monthly charge of $40. The other cell phone plan has a monthly charge of $30 but costs 15 cents per minute. Which equation shows the total monthly cost as being the same? Let m be the number of minutes used in a month.

• 0.10x + 40 = 0.15x + 30

• 40x + 10 = 30x + 15

• (0.10+0.15)x = 40 + 30

• 40 - 0.10x = 30 - 0.15x
