Answer from: Idontreallycare16

he averages for each category can be calculated by taking the sum of the values and dividing by the number of values .

Jan Feb March

wages $2,100.00 $2,300.00 $2,000.00

sum of the values = 2100 + 2300 + 2000 = 6400

number of values = 3

average = 6400/3 = $ 2133.33

donations $210.00 $230.00 $200.00

average = (210 + 230 + 200)/3

= $ 213.33

mortgage $590.50 $590.50 $590.50

average = ( 590.50 + 590.50 + 590.50)/3

= $ 590.50

electricity $101.25 $89.75 $80.00

average = (101.25 + 89.75 + 80.00)/3

= 271/3

= $ 90.33

water $20.10 $22.30 $24.55

average = (20.10 + 22.30 + 24.55)/3

= 66.95/3

= $ 22.32

car loan $172.54 $172.54 $172.54

average = (172.54 + 172.54 + 172.54)/3

= $ 172.54

food $200.25 $220.70 $205.50

average = (200.25 + 220.70 + 205.50)/3

= $ 208.82

insurance $310.50 $0.00 $0.00

average = ( 310.50 + 0.00 + 0.00)/3

= $ 103.50

clothes $0.00 $0.00 $75.00

average = (0.00 + 0.00 + 75.00)/3

= $ 25.00

car license fee $0.00 $120.90 $0.00

average = (0.00 + 120.90 + 0.00)/3

= $ 40.30

average = (0.00 + 0.00 + 45.00)/3

= $ 15.00

average = (18 + 0.00 + 36.0)/3

= $ 18.00

13)

new car $100.00 $100.00 $100.00

average = (100 + 100 + 100)/3

= $ 100.00

average = (80.00 + 70.00 + 75.00)

= $ 75.00

15)

car repairs $0.00 $119.00 $0.00

average = (0.00 + 119.0 + 0)/3

= $ 39.67

16)

miscellaneous $64.50 $59.25 $72.50

average = (64.50 + 59.25 + 72.50)/3

= 196.25/3

= $ 65.42
