Mr. Adams wants to rent a beachfront condominium. Unit 1 costs $1,200 for the week plus a cleaning fee of $50 per day. Unit 2 costs $1,450 for the week with no cleaning fee. What is an appropriate model to use to determine at which number of days both units cost the same amount for the week? a table with two columns, one showing the cost of Unit 1 starting at $1,200 and increasing $50 every row, and the other showing the cost of Unit 2 starting at $1,450 and increasing $50 each row a graph with the number of days for the week on the x-axis and the cost on the y-axis, showing the cost of Unit 1 starting at $50 and increasing $1,200 each day, and the cost of Unit 2 starting at $0 and increasing $1,450 each day a graph w the number of days for the eek on the x-axis and the cost on he y-axis, showing cost 1 starting at $1,200 and increasing $50 each day, and the cost of Unit 2 at $1,450 each day without increasing a table with two columns, one showing the cost of Unit 1 starting at $50 and…
Can you help put this is reduced row echelon form?
live 9 (rectangular) blocks from Tech, and I walk each morning. The trip is 3 blocks north and 6 blocks west; and I have to follow the streets, so I cannot cut diagonally. At each intersection, I must choose whether to walk north or walk west. Thus, I must make 9 choices of which to take, but of course must go north 3 times and west 6 times. How many possible complete trips to Tech are there?
