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.
