Question

When full a 22 gallon tank holds 129.8 pounds of gasoline estimate the weight of 1 gallon of gasoline. If it cost $91.30 to fill the gas tank estimate cost per gallon

Answer 1

keep in mind, estimation is not exact...
estimation.....22 gallons rounds to 20......129.8 lbs rounds to 130 lbs....91.30 rounds to 90

130/20 = 6.5 lbs per gallon

90 / 20 = $ 4.50 per gallon

Answer 2

2 seperate questions
what is the weight of 1 gallon and what is the cost per gallon

weight/1gallon=wieght/gallons=129.8lb/22gal=5.9lb/1gal
weigth is 5.9lb per gallon

cost per gallon=cost/gallons=$91.30/22gal=$4.15/1gal
cost is $4.15 per gallon




if ya wanted to estimate

lb per gallon is 129.8lb/22gal≈130/20=6.5lb/gal=6.5lb per gal
cost is $91.30/22gal ≈90/20=9/2=$4.50 per gal
