An archery range calculated the average speed of wooden arrows shot during a competition. which is the best representation of the average speed?

To find an average, add all the speeds of each arrow together and divide that number by the total number of arrows shot.

example:

Arrow 1:

20mph

Arrow 2:

23 mph

Arrow 3:

23 mph

= 20+23+23 = 66

66÷ 3= 22 mph on average

hope this helps

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
