Question

When eating out, it is customary to tip your server at least 15% of the cost of your meal. The graph shows a 15% tip, t, for a meal that costs m dollars.


Each of the following sets of numbers represents dollars. Assuming the graph is correct, which set of numbers is most appropriate to label the seven tick marks along the vertical axis (15% tip)?

Question 5 options:

15, 30, 45, 60, 75, 90, 105


1.50, 3, 4.50, 6, 7.50, 9, 10.50


5, 10, 15, 20, 25, 30, 35


10, 20, 30, 40, 50, 60, 70

Answer 1

Answer:

1.50, 3, 4.50, 6, 7.50, 9, 10.50

Step-by-step explanation:

The x axis represents the amount of money the meal (without tip) costs.

The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.

So the question is really easy to solve. We see our first point is at (1,1) on the coordinate plane which has the meal costing $10. All you have to do to find the tip is to multiply $10 x (0.15%) = 1.50...

So 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct!

Hope this helps, let me know if you need further or better explanations!
