Ответ:
$3.49 for 450 gallons, 3.40(450), is $1570.50.
The profit difference, 1570.50-1345.50, is $225.
Ответ:
at 0 hours the plane has 422,000 gallons of gas.
after 2 hours it has 369,250 gallons.
subtract to find the difference and then divide by 2 hours:
422000 – 369250 = 52750 /2 = 26,375 gallons per hour.
can also do the full 16 hours:
the plance used 422,000 gallons in 16 hours:
422,000 / 16 = 26,375 gallons per hour.
