Correct Answer: C

Rationale:
To find out how many days Bernard needs to work to make $300, we divide the total amount he needs by how much he makes per day: $300 / $80 = 3.75 days. Since Bernard can only work full days, he would need to work for 4 days to make $300.
Therefore, the correct answer is 4 days.
Choice A (2 days) is incorrect because it does not match the calculation based on his daily earnings.
Choice B (3 days) is incorrect as the calculated result is not a whole number, so Bernard needs to work for more than 3 days.
Choice D (5 days) is incorrect as it exceeds the calculated number of days needed to make $300.

Correct Answer: A

Rationale: Among the provided options, 0.45 is the largest number.
To determine the largest number, compare the decimal values directly. 0.45 is greater than 0.313, 0.3, and 0.096.
Therefore, 0.45 is the correct answer.
Choice B (0.096) is the smallest as it has the lowest decimal value.
Choice C (0.3) is greater than 0.096 but smaller than both 0.313 and 0.45.
Choice D (0.313) is greater than 0.3 and 0.096 but smaller than 0.45, making it incorrect.

Correct Answer: C

Rationale: If \(2x = 6\), then solving for \(x\), we have \(x = \frac{6}{2} = 3\). So, if \(x = 3\), then \(x+1 = 3+1 = 4\).
Therefore, the value of \(x+1\) would be 4.

Correct Answer: A

Rationale: A line that travels from the bottom-left of a graph to the upper-right of the graph signifies a positive relationship between the predictor and dependent variable. This indicates that as the predictor variable increases, the dependent variable also increases.
Choice B, 'Negative,' is incorrect as a negative relationship would be depicted by a line that travels from the top-left to the bottom-right of the graph.

Choices C and D, 'Exponential' and 'Logarithmic,' respectively, represent specific types of relationships characterized by non-linear patterns, unlike the linear positive relationship shown in the described scenario.
