_____ 20. 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. Type your answer in the blank to the left. A. 16 weeks B. 13 weeks C. 15 weeks D. 14 weeks

Substitute the given values into w in the equation to determine the answer. For example: 16 weeks 60 + 30(16) = 480 60 + 480 = 480 This isn't correct because the sides aren't equal. Do that for each answer given....or solve the equation for w by subtracting 60 from each side of the equation and then solving for w. It's much quicker.
