A farmer collects an average of 8 eggs per day from a total of 10 chickens. The farmer graphs the total number of eggs from the 10 chickens over one 30-day month. If x represents the number of days since the farmer started recording the number of eggs, and y represents the total number of eggs collected, which best represents the scales that would be used for the graph?

• The x-axis could be labeled from 0 to 10 with a scale of 10, and the y-axis could be labeled from 0 to 30 with a scale of 10.

• The x-axis could be labeled from 0 to 30 with a scale of 1, and the y-axis could be labeled from 0 to 10 with a scale of 10.

• The x-axis could be labeled from 0 to 30 with a scale of 1, and the y-axis could be labeled from 0 to 250 with a scale of 10.

• The x-axis could be labeled from 0 to 250 with a scale of 10, and the y-axis could be labeled from 0 to 10 with a scale of 10.

A kitchen scale comes with a 100% money-back guarantee that the weight shown on the scale will stay within 0.2 ounce of the actual weight of an item. If the actual weight of an item is 6 ounces, and x represents the number of ounces shown on the scale, which inequality represents the weight readings where a full refund would be given?

• |x – 0.2| < 6

• |x – 0.2| > 6

• |x – 6| < 0.2

• |x – 6| > 0.2

36. Consider the two exponential functions listed - f(x) and g(x). Which statement is true?

• As x increases, Function 1 decreases by a greater percentage than Function 2.

• As x increases, Function 1 decreases by a lesser percentage than Function 2.

• As x increases, Function 1 decreases by the same percentage as Function 2.

• The rates of the two functions cannot be compared.
