Question

An investment of $50,000 is made in a company that manufacturers an item at a cost, C, of $10. Each item sells for $15. If R is the revenue generated for selling x items, which statement is true about the graphs of the equations C = 50,000 + 10x and R = 15x?


Both slopes are positive.


Both slopes are negative.


One slope is positive, and the other slope is zero.


One slope is positive, and the other slope is negative.

Answer 1

Both slopes are positive.

Explanation: The slope is the coefficient of x. For C = 50,000 + 10x the slope is 10 (positive). For R = 15x the slope is 15 (positive).
