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 i need

The bar diagram consists of 20 boxes in a row. The number 15 is written into each box. The time of 20 weeks is represented by the entire row of boxes. When added together the numbers in the boxes come to 300, the price of the camera. Each box represents a weekly saving.
If x is the number of weeks then 15x=300 is the algebraic equation with solution x=20.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
