Question

Li buys supplies so he can make and sell key chains. He begins to make a profit only after he sells 4 key chains. What point on the graph makes the most sense in this situation?

Answer 1

Answer:

Point A makes most sense

Step-by-step explanation:

We are given four points on the graph:

where x is the number of keychains sold and y is the profit.

A (3, -0.5)

B (3.5, 0.25)

C (2, 0.5)

D (4.5, -3)

According to the condition given that he makes profit only after he sells 4 key chains; only point A makes most sense.

Point A(3, - 0.5) shows that 3 keychains are sold, but there is a loss of 0.5

B (3.5, 0.25) shows that keychains sold are less than 4 but he is getting profit of 0.25 which is not possible according to given condition

Point C(2, 0 .5) is again wrong. Keychains sold are less than 4 but he is makina a profit which goes against the condition.

Point D(4.5, -3) is wrong because the keychains sold are more than 4 but still he is not making a profit which is shown in negative.
