Subtract the cost of the magazine to the total cost.
43 - 3 = $40 spent on erasers.
Divide by the amount of erasers.
40 / 8 = 5 erasers
Hence, Jennifer bought 8 erasers for <u>$5 each.</u>
Best of Luck!
Answer:
I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same

What is the mean, median, and mode of 3,8,13,4,9,15,7,8,5,
Stella [2.4K]
Answer:
Mean: 8
Median: 8
Mode: 8
Step-by-step explanation:
Find the average
Mean: 3 + 4 + 5 + 7 + 8 + 8 + 9 + 13 + 15 = 72
Divide by the amount on numbers: 72 / 9 = 8
8 is the average
Find the middle
Median: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is the middle
Find the most common
Mode: 3, 4, 5, 7, 8, 8, 9, 13, 15
8 is most common
