On her way to NY, Jenny spent the same amount for gasoline each time she
stopped for gas. She paid 239.9 cents per gallon the first time; 249.9 cpg
the second time and 259.9 cpg the third time. What was the average price
per gallon to the nearest tenth of a cent for the gasoline that she bought?
:
Assign a value for each fill-up: 3000 cent
:
Find the number of gallon purchased each time:
1st time: 3000%2F239.9 = 12.505 gal
2nd time: 3000%2F249.9 = 12.005 gal
3rd time: 3000%2F259.9 = 11.543 gal
----------------------------------------
total number of gallons: 36.053
:
To find the average price, divide the total cost (3*3000). by the total gallons:
9000%2F36.053 = 249.6 cents is the av cost per gallon
