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.
15 weeks
14 weeks
16 weeks
13 weeks
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
