An aircraft cost 2852 per hour to operate, what is the total cost for 5.7 hours
Hi Sandra;
I like Nancy's answer, but want to add to it.
($2852 hours)
This can also be written as...
(2852 dollars/hour)
However, I think your instructor wants to see the former. I just want to illustrate as much as possible...
($2852/hour)(5.7 hours)=x
Let's cancel units where appropriate...
The hours are in both the denominator and numerator of the left side...
($2852/hour)(5.7 hours)=x
Cancelling units must come before calculations. This is because if your units are not aligned, you have the wrong equation.
($2852)(5.7)=x
The only unit remaining is the $. Your answer is requesting "total cost". This works.
$16256.40=x
