Question

Michelle wants to plot a graph to show the prices of different numbers of helmets. She has to plot the following points:
(4, 99.88), (5, 124.85), (6, 149.82), (7, 174.79), (8, 199.76)

Which of the following best describes how the x-axis should be labeled?

Answer 1

From 0 to 8 at intervals of 0.5
From 0 to 20 at intervals of 4
From 0 to 10 at intervals of 2
From 0 to 6 at intervals of 2

Answer 3

Notice how the x-values have no decimals. So the first answer choice would be illogical. The second choice is also illogical, because why would you want a graph to go all the way to 20 if the values only go to 8?
So...by thinking along the same way, can you tell me if the correct answer is C or D?

Answer 4

its d because c only goes up to 6

Answer 5

thank you so much!

Answer 6

i meant c because d only goes up to 6

Answer 7

Yep. Great job. :)

Answer 8

also could you help me with this one
A solution of salt and water contains 75 grams of water per 150 milliliters of the solution. If 1 mole of water weighs 16 grams, moles of water would be present in 30 milliliters of the solution. [Round off your answer to two decimal places. If you answer is less than one, include the zero before the decimal point.] (4 points)
