Brandy wants to buy a digital camera that cost 300.suppose she saves 15 each week. in how many weeks will she have enough money for the camera? use a bar diagram to solve arithmetically. then use an equation to solve algebraically

20 weeks.

Bar graph: Start with zero, and the next ones (bars) will all increase by a 15 interval over the period of 20 weeks. So 1 bar per week, and there are 20 weeks, with each bar having a 15$ profit difference. Sorry, can't draw it here.

equation: 15x=300
                15/(15x=300)/15
                 x=20

Idon’t know i’m in the same boat
