Sylvester and Erin collect baseball cards. Sylvester has 250 baseball cards and collects 15 cards per week. Erin has 300 baseball cards and collects 10 cards per week. After how many weeks will Sylvester and Erin have the same number of baseball cards? Write and solve an equation to model the problem. Explain the meaning of the solution.

It will take 6 weeks for them to have 360 baseball cards at the same time.

Step-by-step explanation:

250 + 15 = 275 + 15 = 300 + 15 = 315 + 15 = 330 + 15 = 345 + 15 = 360

300 + 10 = 310 + 10 = 320 + 10 = 330 + 10 = 340 + 10 = 350 + 10 = 360
