Brandon 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. To find how many weeks w it will take to have $480, solve 60 + 30w = 480.

Question

15 weeks

14 weeks

16 weeks

13 weeks

Answer 1

To solve the equation 60 + 30w = 480, first subtract 60 from both sides:

30w = 420

Next, divide both sides by 30:

w = 14 weeks

Therefore, it will take Brandon 14 weeks to save up enough money to buy the TV and stereo system for his room.

So the correct answer is:

14 weeks
