What is the formula to calculate the cost of gasoline for running a machine?

Back

Cost = (Gallons per hour) * (Cost per gallon) * (Hours of operation)

Front

If a snow blower uses 2.5 gallons of gasoline per hour, how many gallons will it use in 4 hours?

Back

10 gallons (2.5 gallons/hour * 4 hours = 10 gallons)

Front

What is the cost of gasoline if it is $3.75 per gallon and a machine uses 2.5 gallons per hour for 3 hours?

Back

$28.125 (2.5 gallons/hour * 3 hours * $3.75/gallon = $28.125)

Front

How do you determine the total cost of running a snow blower for 'h' hours?

Back

Total Cost = 2.5 * 3.75 * h = 9.375h

Front

What does 'h' represent in the context of running a snow blower?

Back

'h' represents the number of hours the snow blower is operated.

Front

If the cost of gasoline increases to $4.00 per gallon, what will be the new cost expression for running the snow blower for 'h' hours?

Back

Total Cost = 2.5 * 4.00 * h = 10h

Front

What is the relationship between gallons used and hours operated for the snow blower?

Back

The gallons used is directly proportional to the hours operated.

Front

If Maggie runs her snow blower for 5 hours, how much will she spend on gasoline at $3.75 per gallon?

Back

$46.875 (2.5 gallons/hour * 5 hours * $3.75/gallon = $46.875)

Front

What is the significance of the number 2.5 in the context of the snow blower?

Back

2.5 represents the gallons of gasoline consumed per hour of operation.

Front

If a snow blower runs for 2 hours, how much gasoline will it consume?

Back

5 gallons (2.5 gallons/hour * 2 hours = 5 gallons)
