An online furniture store sells chairs for $50 each and tables for $250 each. Every day, the store can ship no more than 36 piec
sattari [20]

Answer:

All possible values for the number of tables that the store must sell in order to meet the requirements are 9, 10, 11, 12, 13.

Step-by-step explanation:

Let x be the number of chairs sold and y be the number of tables sold.

Chairs are sold for $50 each, then x chairs cost $50x.

Tables are sold for $250 each, then y tables cost $250y.

In total, x chairs and y tables cost $(50x+250y).

Every day, the store can ship no more than 36 pieces, then

x+y\le 36

Every day, the store must sell at least $3,400 worth of chairs and tables, then

50x+250y\ge 3,400

If 23 chairs were sold, then x = 23. Substitute it into the inequalities:

23+y\le 36\Rightarrow y\le 13\\ \\50\cdot 23+250y\ge 3,400\Rightarrow 250y \ge 2,250,\ \ \ y\ge 9

Thus 9\le y\le 13

This means all possible values for the number of tables that the store must sell in order to meet the requirements are 9, 10, 11, 12, 13.

A system of equations is given below. y = negative 2 x + one-fourth and y = negative 2 x minus one-fourth Which of the following
Ronch [10]

Answer:

  They have the same slope but different y-intercepts, so they have no solution.

Step-by-step explanation:

The slope is the coefficient of x. In both cases, it is -2, so the lines have the same slope. (This eliminates the last two answer choices.)

The added constants are different for the two lines, so they have different y-intercepts. This means the lines are parallel and do not intersect.

A "solution" to the system of equations is a point (x, y) that satisfies both equations. Since the lines have no points in common, there are no solutions. (matches the first answer choice)
