Median: 23
Mode: 27
Step-by-step explanation:
order from least to greatest:
1, 15, 18, 22, 23, 25, 27, 27, 31
mean: add all the numbers and divide by 9 bc thats how many numbers there are so that means the answer is

Mode: to find the mode you look to see what number is repeated multiple times, so the mode is 27
For the first question you shade in the bar to the 20% mark as she has saved 20% of the money needed for her jacket. To complete the bar you add the amount of how much each percentage is in dollars. We know 20%=$15 and the percentage goes up 20% each time so you keep adding $15 on. For question 2 the bar is half way between 0 and 20 and half of 20 is 10. As 10 is half of 20 we half 15 to get $7.50
