For this case we have the following equations:
revenue: y = 4x
cost: y = 1 / 2x + 280
We must match both equations:
4x = 1 / 2x + 280
From here, we clear the value of x:
4x-1 / 2x = 280
7 / 2x = 280
x = (2/7) * (280)
x = 80
Answer:
jason needs to sell 80 posters so that the cost and revenue are equal
<span>The input variable is the number of rowers in a rowboat and the output variable is the speed of the rowboat. When you input the number of rowers into an equation, you should be able to find out how fast the rowboat is going. The speed of the rowboat is directly proportional to the number of rowers.</span>
If you sum these two numbers up, you get 2n + 1. 2n will always give you an even number. Adding a 1 to any even number will always give you an odd. Therefore, a sum of any pair of consecutive numbers is always odd.
Example, 4 + 5 = 9; –8 + (–7) = –15.
Step-by-step explanation:
Rhombus since the other 3 have lines that go accross the graph horizontally for 3 squares.
(original - new)/original = discount
65-42.25)/65 = discount
22.75/65= discount
.35 = discount
multiply by 100 to put in percent form
35 percent
