morty needs $480 to buy a Tv and stereo system for his room. he received $60 in cash for birthday presents. He plans to save $ 30 per week from his part time job. The equation model for this situation is 60 + 30w=480. How many weeks (W) will take him to have $480

Hey! So this is pretty straightforward. You're given all the information already and now you just have to do some calculations.

60 + 30w = 480

You can start by subtracting 60 from both sides

30w = 420

Now you need to get w by itself so you have to divide both sides by 30 and you will end up getting

w = 14!

It will take him 14 weeks to save up

60+30w=480

30w=420

w=14 weeks
