Step-by-step explanation:
Round trip travel: 2*15miles*$0.45/mile = $13.5
Equipment: $84 + $15.50 + $47 + $32 + $22 = $200.50
Tax = $200.50 * 5%/100 = 10.025
Lessons: $25*10 = $250
Total cost = 13.5 + 200.5 + 10.025 + 250 = $474.025
1/2 can't be rounded so its 1/2 still.
3 4/11 rounds to 3.
2 1/0 rounds to 2.
Median
Median is the mean of 18 and 32 because they are in the middle, so it's 25. Median is the best representation because most numbers are around 20-30. 115 makes the mean go super high, which is not good, 11 drags the mean down, which is not good either.
Extras:
Mean: 11+11+18+32+34+115 =
221 divided by 6 =
36.88
